Dewalt if you're reading this, this guy has easily sold hundreds of these -send him some free kit!

I kinda became a DeWalt fanboy about 20 years by accident. I bought one power tool. It worked great so I bought another, then another etc... My first tool is over 20 years old and still going strong. This screwdriver will be my next purchase.

Just built one of those cheap entertainment centers and screwing everything together with that tool made it a breeze. I also was amazed at this tool

It’s my favorite tool too. I got It’s few years back for $40 at home depot. I also purchased the flash light too. Both work very well.

One of my favorite tool! Great review. Also you can change the bits with one hand, when you pull the ring down it pops the bit out. Good engineering.

You use mine damn much, it's crazy how often it get pulled out 😁👍 Mine had gotten rained on after not being able to find it after a couple months during monsoon season in AZ. Took the battery apart and noticed some corrosion and rust on the internal battery tabs and used my Milwaukee 12v dremel with brass rotating brush to clean them all off and voila good as new.

I just bought one for work and I couldn’t figure it out! Sir, you just blew my mind! This tool is so cool.. thanks for showing me how to use it

Hey! Greetings from UK! Ive injured my hand, but still need to work and this is exactly what I need! Thank You so much for taking the time to carry out a very thorough review, it really has helped me decide fast what I need!! Thank You!

Great tool! I just bought one from Amazon along with same screwdriver attachment set. The DeWalt gyroscopic screwdriver is every bit as good as you say it is. I highly recommend buying one.

Amazon is currently selling the DeWalt 32-pc Screwdriver bit set that you showed us for $32.60. However, I was able to buy DeWalt's 35-pc Screwdriver bit set on sale at Lowes for 15.98.

You’re on your way to a million subscribers....great review.

Thank you for this awesome review. Getting this tool in town today. I hope, that you are getting paid for these reviews because you advertise them well.

Cool, i just got mine today... i was wondering how to unscrew and screw when i was testing it... clever little thing it is... now i gotta put it to some use... yeeeepeeeee

I couldn't figure out how to use this tool. I was going to return it to the hardware store until I watched this video. A simple explanation on how to use this sweet gadget. Thank you, UC physics major dude.

I just ordered one. Thanks for doing the review.

It uses a mems gyroscope and accelerometer chip. The gyroscope can detect angular momentum while the accelerometer detects orientation. It uses the same tech that keeps drones in the air. It seems like black magic, but it's really just horrendous math being done in an 8 bit microcontroller at high speed.

Been using screwdrivers for over 50 years and this is my goto for about 85-90% of my around the house needs. Not a gimmick, it is a natural extension of movement- righty tighty lefty lucey

Thank you for the review! I work in Data Centers and I wanted tool that would help me do my work easier and this tool has been a God Send so far..... as you can imagine taking out a hundred screws during the week is not fun when you have to do it by hand! Cheers

Just pick-up mine today from Lowes. Will try it out at a customer call.

You just converted me from Bosch Go2 to this Dewalt. Good review!

3 gyroscopes; Pressing the button will "zero" out and watch for changes in each gyroscope

Neat tool. Would love to see even one holder for extra bits built into the tool.

The DeWalt XR impact has 3 settings. When it comes to stuff you don't want to over torque the 1 setting is super soft.

Have 2 of those and the one that rotates the handle to turn into a drill love'em all!... And unlike the competition it can power a 2" Course Drywall Screw into a stud flush.

I just bought one 2 days ago. The best tool I have ever bought! That and the Bosch GLL100g laser level I bought a couple of weeks ago.

Just purchased one!! Thanks !!!

More than what I wanted to spend, but I am ordering both because of this review. ARE YOU LISTENING DEWALT?

You can't talk a man out of his toy. Good vid.

I'm on the dewalt platform but I prefer the variable trigger on my no cry screwdriver, just seem to use it more.

We can expect it's the same "gyro" mechanism used in smart phones, which detect rotation in 3 planes, as you speculated. But, these devices also detect _orientation_ in 3 planes (a 6-axis sensor). If I'm watching you correctly, it seems to detect the orientation at the time you depress the button, and then knows which planes on which to detect rotation, and thus knows when you rotate around the axis of the drive.

Thank you for this review.

Likely has an accelerometer that works with the gyro to keep track of it's orientation.

All of your tools are clean.

I hadn’t figured it out because I hadn’t read the instructions. I thought it was faulty. Thanks

My dad still uses a manual screwdriver all the time. I just go this and the kit that comes with a bunch of different heads for him.

Great review

Please consider doing a review on the flashlight that uses the same battery

Thx for your sincere amd compelling video. I’m was thinking about the Bosch but the Dewalt seems to be a much better decision. Removable batteries are a huge bonus. Sealed batteries usually mean you have to deal with an illusive manufacturer. I do not own ANY DeWalt tools. This will be my first! Thx again.

Very good review 👍 Would have helped if you had turned a screw in and out.. thanks

Can you add 90° attachment for tight spaces ? Wouldn't that be cool !

There's a levole in side when you that makes contact 👍🇨🇦

I love that thing

I switched to Milwaukee a while back and never looked back. In interested in this one though.

Nice review thanks! I am looking for a small tool to use as a small sander on art projects. I paint on wood & like to do light sanding through the paint layers. Does the gyroscopic aspect of this tool hurt your wrist?

Excellent review ❤❤❤😊

I have one but battery and charger are misplaced. It is working if i apply 7.4v directly from veriable power supply?

Could you attach cleaning scrubs to that?

I just hated the gyroscopic function and gave it to a friend. I have a Worx one, and a Milwaukee one now.

Love that you have a degree in physics and are impressed! I am a 75 year old woman who has been so frustrated at not being able to do things I used to (Torn rotator cuff, arthritis in hands, etc) that I am hoping this would at least help with screwing things!!! What do you think? Even holding a quart of water for more than a minute or two is a problem. I have to take my jars out and have the mailman open them for me. A normal can opener is painful and slow. I can't screw or unscrew anything:) How much does it weigh? Can it drill also? Will it do one of those right angle thingies? What is the link for the charger? ** I just went to the amazon link for the screwdriver and bit set, which is the only way you linked the screwdriver, and it is not available. Please post a link for the screwdriver only so we know which one. Thanks!

Thank you very much. Is there a set of longer bits available too?

Can be the torque adjust/tuned?

amazing!

That giro feature makes it do something no other electric screwdriver can do. Variable speed operation. To most experienced carpenters clutch settings is pretty much useless. We don’t have the time to mess with it, so variable speed is much faster

It works on fusion reaction

May be it has the same sensors in it like a smart phone - so it works also upright

Which one would you recommend, this or Bosch Go 2? :)

I am having a problem finding a battery n charger for it i just pick one up with out a battery any idea where i can find one thanks

Do you think it needs a clutch so you dont over torque say plastic switch plates? They have a differetnt model that is clutched and folds

It's a novelty. Sure it's fun to play with but why twist your wrist when you could simply press a button on a non-gyro screwdriver. In a tight spot do you want to be twisting your wrist or pressing a button?

Hello Friend, I did enjoy to watch you video! but can you tell me how long does the battery last?

How do you turn the light off ?

Same technology is used in those segways… amazing

Am i mistaken or this version does not have torque regulator?

I agree

Good video

Hey, I've only had mine a month or so. It no longer works. It will turn on briefly when I push the paddle. Then the motor will come on very infrequently and sometimes it will turn, but I can't then turn it in the other direction and it stops responding after that.

Hello, how does the DEWALT DCF 680G2 differ from the DCF 680N2?

Unfortunately my gyro stopped working. It was only 4months old so getting a refund. It is a shame because it is a fabulous tool

it works because it is a gyro chip, not an accelerometer chip. when you turn your phone sideways and the screen rotates, thats an accelerometer, It knows which way is down. A gyro chip doesnt know which way is down, but in this application it doesnt need to. In fact, the gyro doesnt even know how much you have rotated it. Then how does it work? Well, the gyro senses how quickly the screwdriver is rotated, and the little processor chip performs an integration calculation to convert from rotational speed, to absolute rotational distance. I dont know the exact algorithm they are using. Furthermore, I would bet they have a combo gyro and accelerometer sensor in one chip because those are commonly used in cell phones so they are dirt cheap and they just ignore the accelerometer. The gyro chip itself is amazing. its a micro electro mechanical system (MEMS for short). inside is a tiny vibrating piece of sillicon attached at the base to a deflection sensor. As the screwdriver is rotated, that tiny vibrating piece is bent to the left or right because it is resisting the changing angle, kind of like that science experiment where you hold a spinning bicycle tire while sitting in a desk chair and as you tilt the bicycle wheel, you start to spin in the chair.

Thinking of getting one still recommend it? I kinda want the other version with clutch and swivel handle

I never even considered one of those cause I have a drill

I got a question what's the battery output on a full charge I know it says 8v max but whats the actual voltage???

DeWalt should make the pistol style with just the forward/reverse switch & withOUT the bloody gyroscopic feature!!!

Isn't it just an accelerometer inside, like in a cell phone?

What kinda torque does it put out 35-45 inch pounds I'm guessing? Good for dash work and interiors of vehicles?

If ur buying from Amazon UK - it will come from US and the charger is only set up for 110V so ur gonna have a problem. Be careful !

How well does this work as a drill? I have an impact and a highspeed but i wanna get something smaller all my bits will work for. I need it for drilling into resin models to place magnets. Any recommendations?

Add a clutch and it's perfect!

Does it has torque adjustment

Did you know you can unlock and twist the grip to make it a ‘pistol’ grip?

Gyroscope with counter weight

Probably a weighted multiracial spherical base.

Will it work with a 90 degree bit?

Do you think this would work building R/C Cars?

If it had usb type c, I would buy immediately.

In UK, can't get these for love nore money :(

Can you use it with drill bits?

The 2 i owe suck!!! I thought that the first one messed up because i droped it. So i got a nother one and it sucks to.

It has what every smartphone has, an accelerometer. BTW… you need a tripod.

damn this is too big... need one for hard to reach places with very small amount of room.

Hello Physics guy the gyroscope inside is a MEMS (Micro-ElectroMecanical Sensor) accelerometer

Pistol grip version with the clutch is better.

:D Except that it is not intuitive. It should spin in the direction that you turn.

How does it do that? Hm, you said 'gyroscopic', so maybe it uses a gyro? ;-)

It's not black magic, they are just using 2 gyroscopes 😅 Your phone is using multiple gyroscopes too

Crap I just returned mine cuz I didn't realize how it worked. I thought it was broken

Well, your first mistake was getting a degree from the University of California. Seriously though, that was a pretty good review. Keep it up.

No chuck... tsk tsk, I wouldn't get it.

Everyone like 10 inches

You should have started out showing how it works.
