Overall impressed with the quality and lack of lag time with this set up. Considering the substantially lower cost the limitations of battery life (~3 hours) and smaller field of view (compared with much more expensive options) is more than reasonable.
This device works, but doesn’t fit securely to the helmet mount. The locking mechanism needs to be more robust. It can be pulled off with little effort, even while locked.
It is really a really good design arrived fast, i struggled to get it on my helmet from user error butnonce i figured it out it went on like a glove, i have two viper 4.0s that i intend to mount on it and cant wait to use them, been very happy with my current and past orders the quality of the viper 4.0 night vision as well is accurate to the videos maybe even better quality.
Works great, I added a counter balance weight to the rear of the helmet to steady it. One thing that would help is having slightly different thickness pads inside to adjust the fit. Mine is just a little tight. Other than that it works as it should.
Very good for the price!!! Some wobble but not too much with retention cord hooks solve that!!! Start selling the retention cord hooks that mount to helmet!!!
