Just installed this one in my Type-s. I did the front/rear 4K/FHD combo. I love it. The footage I have been able to capture has been very helpful.

What's your opinion of the polarizing lens add on? Is it worth it?

While the look is clean I have 3 issues with this. 1) The lens is not adjustable. There should be some ability to as I believe there is too much of the hood being show 2) No sound to identify that the unit has powered on. I believe some of the earlier models had issues just dying after a month of use which was resolved. If this stops working you might not notice that small dim LED which shows if it is on. Even then you have no idea if it is working 3) With no voice you won't know if there is an issues with the microSD card With these issues IMO I would say to get a Viofo over this. Yes it might not look as hidden but I prefer functionality and knowing my device works or has some sort of issues instead of coming into a situation of an accident and then not having the video which I would need.

I see they have a 2 channel version as well. Any plans to review that one? How does this compare to other dash cams, like Viofo and Vantrue?

Does it disable the auto dimming mirror or is it still working after installing?
