Can't wait for your review of their newest product line - GTR 4, GTS 4 and GTS 4 mini

This guy is the only guy in KZfaq letting us know that this watch is not worth if you expect it to be a good fitness tracker. I had a T Rex Pro and the heart rate measurements were really bad, not a single review stating that i was able to find at the time. Ended up buying a Garmin and I'm happy.

Absolutely incredible and informative videos 👏. Just randomly I clicked on your video and after watching your multiple videos I am so glad that you are covering all the aspects smart watches throughly which are mostly just sold on basis of specs and features (of health) to attract customers. You videos give detailed insight for those who are seriously consider smart watches for their fitness purpose. Your videos are really helpful. Looking forward for more such videos. Good Days 👍.

The testing of the GPS accuracy is a really good addition!

Looking forward to Amazfit GTR 4 results :) Newest firmware + new sensors.

Best reviews on KZfaq - so detailed and telling it as is.

Well done , keep it up. Really enjoying these videos and your style of presentation

Thanks for the reviews and all the data comparisons 👍

Dear Rob, One idea for your channel: 2021 is coming to an end and I think "best-of-videos" on the different dimensions might attract MANY MORE viewers than in-depth reviews of individual watches. So, for example, you could make a video on: - Best watch/tracker for sleep analysis - Best watch for exercising - Best health watch Etc. Also, an idea could be to optimise the titles using Google Trend, Answer the Public and special marketing tools for KZfaq. I really think you deserve an international audience which should be 10 or 50 times the size it is now. ALL THE BEST! Groetjes uit Berlijn! PS. Your do one-in-a-kind work! Best smart watch tests I have seen on KZfaq! So glad I discovered you before buying a watch. Very unsure now what to buy, because basically every model sucks in at least one dimension, haha.

Ich mag deine Videos, die Zusammenfassung ist mir am wichtigsten 👍 Danke 🙏

I was wondering if you could every do a full comparison video of each and what you recommend them for. Maybe a list of top 5 for 2021? Love your videos!!!

You are awesome! Thank you for such a great review!

Have you thought about doing a retest? I bought the GTR 3 one week ago. The heart rate during workouts seems much more accurate in my case. Yes there is a delay on lowering the heart rate, but compared to your diagrams, in my case the heart rate diagram seems much more accurate and realistic (the hr goes up a decent amount near the end of each weightlifting set and it goes down pretty low especially towards the end of each break). There is a chance that hr tracking has improved with updates. Amazing analysis by the way!

Good job, end of the year we want a top 5

beneficial review that gives you an authentic description of the GTR4

Hey eagerly waiting for amazefit gtr 4 review 🙏🏼

Thanks for the review!! Would love to see Huawei Watch GT 3 review soon

Thank you so much for these reviews! I was really struggling trying to decide which Watch to get, after my Amazfit GTR2e unfortunately cracked. (It's really only the glass, but the company responsible for repairing tasks in Germany wanted like 95€ , whereas I could get a new one for 90€.. ) This was my 3rd Watch from Amazfit so far, but I always had a feeling, that the HR monitoring is somewhat off. Your videos confirms my assumption. I was thinking about getting the GTS 4 (or mini), but I don't think the HR monitoring will be much better than what the GTR/GTS 3 can offer. I will probably go with either the Huawei GT3 or try the Huawei Watch Fit 2! So all in all; Danke für deine ausführlichen Videos!

Reliable review as always, anyway this is expected in this watch, I like to wait the BipUpro and Neo review since they are included in the video. I'll get the Mi watch next month.

review the watch again with the new frimware update please 🙏

What a fantastic review, as always.

Thanks for the review. There was a KZfaq review that showed a heart rate test result of the gtr3 pro. Although the review seemed unscientific, the results however per the video were great for the watch. The title of said video: "High Intensity Heart Rate Accuracy Test of Amazfit GTR 3/GTR 3 Pro Review" by WesKnows. Curious if the pro version is better.

Hi Rob, thanks for all the great videos. They are really very helpful in helping us determine which smart watches to buy. Would you please make a review of the Amazfit GTR 3 Pro. It is a good watch but I have no idea if the Heart rate measurement was imptoved in the Pro version since in your review of the GTR 3, Heart rate measurement was its worst feature. There's a new Xiaomi watch - Xiaomi Watch S1 that has great features and I would really love to know their performance with scientific tests.

Looking forward to Amazfit GTR 4 review!! :D

I love your informative videos. Could you also check whether Amazfit GTR 3 / GTR 3 Pro were keeping accurate time like Apple watches? Specially when GTR 3 Pro has Wifi, it might able to sync time with NTP time Servers.

Waiting for the update on your GTR 3 to see if there are any improvements. Cheers!

Nice review as always, just a request if you are reviewing Fitbit daily readiness score review please also include new heart rate data(after update)

Wow your channel is amazing, solid work! I've deleted so many watches from my wish list because of your channel lol. I guess I'll stay with apple watch for now. Could you do the SE by any chance? Keep it up!! Cheers

Hi, and Thanks for the review. Are you planning to re-review the watch again? I heard that it gets better with the new update!

Excellent. Companies would just put these in and sold off as marketing. But with your reviews it pits accuracy down to the core albeit some would say it is just in a smartwatch but. Higher tier ones do get better sensors

This is the only review smartwatch enthusiasts should read to save time !

Accuracy, thats the one word i would use to define your channel, great video and yet again, Amazfit performing poorly ( and yet again another model i will avoid to buy) I am looking for a better sleep track + gps for workout (including daytime sleep track). I know, i have seen the fitbit videos and i know they are at the top, however i am afraid of they just breaking it, i had 3! Charge 3 in the past ( I bought 1 + 2 warranty replacements) i dont want to put any money on fitbit. I am doing ok now with Mi band 5 so far, just hoping than Mi, Amazfit or Huawei come show up with a better, affordable option, in the meantime i stay tune with this superb channel! cheers!

Bummer, I guess I will return the GTR 3 that I purchase. Again thanks for the reviews. This is really sad because I thought that other you tubers where saying how good it’s the GTR 3.

Great review as usual. Please review Mobvoi ticwatch pro 3 ultra. Huawei watch gt 3.

Thanks bro

If I may... try to set the watch tight. I noticed with t-rex pro that I have to set it tighter if I want a good measure of HR. I also noticed differences between the two arms.

Best reviewer for wearables!!! Keep up the good work! I will not buy GTR3/GTR3 Pro. I don't believe GTS 3 will be better than GTR3 , so GTS3 is also off from my list... I can't wait the review for the others from my check list: 1.Huawei GT3 (I hope will be accurate like Apple watch and will add emoji support) 2.Amazfit GTR3/ GTR3 Pro (❌⛔) 3.Amazfit GTS3 (❌⛔) 4.Xiaomi Watch 2 (aka Xiaomi Watch Color 2 global edition, I can't wait the global announcement)

that's why I went Apple watch. After Garmin I am much happier of accuracy of my HR and GPS> Charging once per 2 days is ok tradeoff of the accuracy of sensors

I think we need an updated review on this watch or the gtr 3 pro with updated firmware!!

Spinning is typically one of the easiest exercises for an Optical HRM to get right. 😬 Great video as always! I'll be curious to hear what you think about some of the Polar watches for sleep tracking.

Just to be clear, to get more accurate data from GTR3, one should get the latest update - Amazfit did fix some issues and now this watch are getting really close to Polar tracker

Please review amazfit gtr 3 pro, with new updated version..

I have no interest in buying this product but Ill watch the video because you go so indepth with your analysis. Ill be curious to see what you say.

The part about heart rate monitoring is simply not true. I watched your review before I bought my GTR3 Pro and you nearly convinced me not to buy it. I did anyways and am I glad I didnt listen to you. Well, at first there were problems like, workout restart and battery drain but to my surprise they fixed it with an update! Workouts can now last as long as I want and there are no restarts. Also, the battery lasts 7 whole days with 4 times a week workouts and all day measurments of all things but without the AOD. I cant say anything about the sleep monitoring as I dont have the headband thing to test it. But what I can say for sure is that the heartrate sensor always picks up the changes in my rithm. Every time I pick up the speed while running and my heartrate goes up, the sensor noticed it. I cant say does it measures it accurently (I dont have a cheast strap) but it pick up every change in my heartrate. Sorry for the long comment and bad English, but I would really like to see your rereview of the watch, cuz I love to watch your videos and I love my GTR 3 Pro!

GTR3 PRO! Please 🙏 In the name of Science 😁 Amazfit Stratos should be interesting, too 🙄

hey Rob, waiting for the amazfit gts TQS reviews!

I have had a fitbit charge 3 for a long time and was thinking about this one looked nice, great battery and good set of features. Now with watching your videos I will not be going that way. Got to figure out what I am thinking wanting to spend under $250.

Another excellent review and another watch to avoid. Can the Huawei GT3 do any better?

Can you please do a Huawei Watch GT3 accuracy test? I wonder if Huawei improved their sensors as well as their accuracy

Please do a video on Samsung watch 4 after the update as samsung claims they had a new heart rate algorithm you are videos are amazing by the way thanks

Good Job again, but especially for sleep Tracking Garmin Venu 2 cant be as that worse in Graphic are you Sure for it?

Hello! I've been enjoying your channel lately bcs i'm currently looking for a new smartwatch. I've been eyeing Amazfit GTS 3. I wonder if you have a plan to do a review on it?

Still no firmware update? It sucks that they can't ship the watches with working firmware =/

Thanks for all your great reviews! Are you planning on reviewing the GTR 4? Or at this point, have you given up on Amazfit lol

Do the garmin fenix 6 review pls, much support on your work!

Are you going to review the Amafit GRT 3 Pro...could be interesting if that version has been improved or not....

Hello, are you planning to review Amazfit GTR4?

Are you also going to test the GTR 3 Pro?

Here's the thing. I have been using it for a week now. So what i found out is that it is accurate if you wear it correctly just as you saw in your last bike ride where you got really accurate heart rate measurements. The problem with the GTR 3/pro is that slight deviations in the wearing can make it inaccurate. So make sure you are wearing it properly. Also I am using an updated firmware so that might also have a role in it. Cheers. And a side note about sleep tracking, well i wouldn't really care if my rem was a bit inaccurate but would it the deep was too inaccurate. So i am fine with it for now. Thanks for the review btw.

Thank you for this test. I wanted to buy this watch, but why would I need a device that incorrectly shows my heart rate? Have updates improved heart rate readings?

could you analyze versa 3? They say it has improved a lot with the latest updates

You should do a video about smartwatches that you would recomend.

Wonder how the GTR4 is improved if at all since they use a larger sensor to collect more data.

Thanks for this info do you have video for the gtr3 pro?

I was waiting for this video I guess the GTS3 and GTR3 pro would be the same because they’re using same sensors

Dude, your videos are amazing. Thanks for the all the efforts you are putting. Can you make a review for GTR4?

please review on Amafit GRT 3 Pro...

Are you planning to check the accuracy of the Fitbit Charge 5's ECG? Was included in the latest update.

Will there be a video after the update?

Thank you! Another KZfaqr compared the GTR3 PRO to the Polar and claimed very high accuracy. You proved that this is not the case. They share the same sensor. Please update re: wrist positioning as this point is interesting.

I have this watch and I often wandered if it picks up my heart rate and speed correctly whilst cycling. In my experience after I'm starting to sweat seriously under the watch's sensor, the heart rate monitoring fails completely, showing resting heart rate during an intense unaerobic sprint session. It mostly works fine if I periodically take it off and wipe the sensor of sweat. I also suspect that it picks up my cycling speeds wrong. I haven't been able to verify it yet but I think it under reports speed by about 7-8kmph, which is okay while running, but with cycling it gets annoying. Especially if you want to track your trainings with better accuracy.

Wow surprisingly inaccurate heart monitor, great review as always, interested to see how the new oura ring 3 and huawei gt3 shape up as they have new sensors in both.

Hey, is it possible for you to test theAmazfit Bip U pro? N also clarify what NYSE version refers to. Thnx in advance.

Under ZEPP > Profile > GTR 2e > Health Monitoring > Activity detection (When watch detects that you are doing exercises, it will automatically increase the detection frequency to guarantee the accuracy of heart rate data during workouts". I wonder if this is turned on when reviewing the watch?

I bought a Huawei watch gt2 pro because of better heart rate monitoring than Samsung galaxy watch 4, especially during running exercise. Thanks for the info!!!

I wonder how much difference a 3rd party strap could make. I'm debating finding a different watch and returning my GTR 3 Pro. I bought these nylon bands that help the watch sit much more flush with my weird wrists, but I have no other heart data tracking devices to test against.

Thanks for your Video. You did your test with latest Firmware Update? There was approvement in heart rate messurement Band GPS Signal i think. You can also do same test with GTR 3 Pro, this watch has also slight differences in Hardware

Garmin Venu 2 seems to be in a wrong place on the graph of Devices' comparision (6:44 - 7:25). In the video of Fitbit Charge 5 tests, it' s ranked in much more higher position which is more realistic.

Hello Would you recommend I go for Garmin instinct or Polar Vantage M over this?

Did you have stress monitoring enabled? I have read that it heavily affects the accuracy of Amazfit devices. The users who suspected this noticed fluctuations every 5 minutes, which is how often the watch checks stress levels if turned on. I’d love a confirmation considering you’re in a unique position to test the reliability of these watches and trackers. Cheers!

Yesterday I received an update.The update Is about heart rate algorithms..I hope now It Will Be Better..thanks for your reviews!

Hi. Any plans to do one on the Ticwatch Pro Ultra?

Please test gtr 3 pro.

Hi Rob, you have many followers begging for the Amazfit GTR 3 pro to be tested! We do appreciate the work and effort you put in and would highly appreciate if you can put nip this one in the bud. Cheers 👍

what about GTR4, when do you estimate you will test it?

wht i more concern for smartwatch is calorie burn. could u do video which smartwatch do track calorie burn accurately?

hello, have you tested the watch with the latest upgrade version of october the 31th witch correct the heart rate accuracy

Bought a Amazfit GTR3. I really loved the Zepp app. Very user-friendly and easy to understand. I also loved the design of the clock. It is also very easy to use. BUT... after training and cycling with the clock for a couple of days I was very disappointed. The heart rate measurement is beyond horrible. The clock measured my heart rate to 60-80 when if was clearly near my max about 165! It did this several sessions. I had to return the clock. Don't buy it. I ordered a Polar Grit X, will see if it's reliable.

oh my goodness....i just bought 1...,luckily i still have a chance to return the goods... amazfit nowadays released GTR4 GTS4 GTS4 mini, would you test these new watches in future? Please!!

Apparently firmware 8.18 improves hr tracking dramatically, could you test with new firmware?

Please perform a test of Honor GS Pro sensor test. I am using it for long time but not sure about the accuracy. Please.

Any chance of having a Review of the GTR4 now?

Please do a test on amazfit t rex pro

I was waiting for this watch for a whole 4 months before it arrived in my country. One of the most elegant smartwatches, if not the most elegant. Very intuitive, very customizable, with an attractive interface with very cool graphics. It has the smartest watch faces of any other brand. Sleep tracking seemed accurate of the time I went to bed and extremely accurate of my wake-ups during the night. There was no way of checking the accuracy of the sleep phases, though, but the sleep score was reflecting my overall mood in the morning. It has limited multitasking during a workout, with access to the music player and phone calls only. When the workout is paused, the multitasking is unlimited to any function. Music player buttons are very INsensitive to the touch. They need a prolonged touch and to be pressed several times before they react. Not very convenient during a workout. Battery life was crazy with an average consumption of 10% daily with all the metrics on and set to the most frequent intervals and with a weekly usage of the GPS for about a total of six hours of operation. This is where the serious weaknesses of the watch begin. I got this watch mainly because I'm a cyclist and I do most of my daily transportation on my bike. I may do up to a hundred kilometers weekly. No matter what combination of GPS settings I used, the GPS was inaccurate with the routes being recorded over buildings in erratic lines, and with curves being shortcutted to diagonal straight lines. Stopping at traffic lights or junctions was automatically picked up immediately and paused. Resuming was picked up within the first 10 to 15 meters. However, the Zepp app would not connect the dots between pause and resume and they would show on the map as gaps. Not a big deal but the problem got worst when the pause was more than 10 minutes, during a visit to a store or a stop for a coffee, for instance. The watch would not pick the restarting of the activity. In one route, a total of 19,4 km was recorded down to 4,6 km. After this incident, I noticed that the watch needed to be resumed manually after having automatically paused for more than 10 minutes. Not at all convenient, as I tend to get forgetful. That's why I needed a watch that I could rely heavily on its automation, but unfortunately, it turned out to be unreliable. However, the HRM and SPO2 seemed to be reasonable with no irregular spikes or ebbs. Additionally, after the third week, I noticed a battery drain. On the third recharging, the watch was charged in the evening to a full charge, I put it on and lay latent until I went to bed. By the following morning, the battery charge had dropped to 66%. I was really sad when I had to return the watch for a refund. Even though the watch is not serving my own needs and lifestyle, I would still recommend it for someone who would use it to track their overall wellness level in a lifestyle different than mine. P.S. I was informed that two consecutive updates fixed the issues I was having, so I rebought a new one. It's been 3 months now and I haven't regretted it. I love it! 🧡

I've been using the Pro version for 2 months, and I'm quite satisfied with its heart rate. So I'm wondering if you can do a similar wonderful review on the Pro version.🤣

Hey please make a new review with the updates firmware like the MiBand 7. Because I believe it has improved a lot. I don't have a Polar heart rate strap but I use the oximeter what I used when I had covid and the measurements are 90% of the time accurate. So please consider retest.

Exists a differene between gtr 3 and pro version...gets better?

Have a try GTR 4, please! ;-)

Please do huawei gt 3 🙏🏻🙏🏻

Interesting and informative.... Regarding heart rate measurement, could the tracking interval play a part in the result? As is, the interval is set at 10 mins apart
