I've had an Innovv K2 on my F6B for a few years and 26,000 miles now and it's been trouble free. The cams have been unaffected by rain and carwash wands. It has both front and rear facing, wide angle cams, both of which work very well. With a big SD card it holds days of video before it starts over writing the older videos. The sound is horrible however and to control the settings easily, you need a smart phone.
It paid for its self on Labor Day when a lady pulled out of a hidden drive a short distance in front of me.
I was knocked out for a short time and the bike received just under $7000 in damages. Thankfully my front cam clearly showed her pulling out in front of me. Since it's still being argued by insurance that's all I'll say about the actual accident.
I will say my helmet was undamaged since it was strapped over my backrest.
I couldn't shave my head for a while due to it's contact with the pavement, but it looks about the same now as it did before. Guess I really couldn't expect an improvement in that department.
Although I still have a headache, a shoulder that pops constantly and a black toe I only missed 2 days of work and have been riding to work again for weeks.
The camera system was a game changer and I'd advise every rider to have one.
