Dragontouch uw camera works!
I had an early go pro, it died, and I tried a couple of other cameras. The vision 3 pro by dragon touch has worked great! basically the same underwater housing used by a lot of cameras, I have had no problems down to 100 feet. I have changed batteries between dives to be sure I have power, but I have never run out of battery power, so no complaints. For the price, I feel very satified.

A good purchase
Excellent night visionCamera works great! The connection is a little slow at longer distances, but it doesn't affect usability. Setup should be pretty easy for the experienced, I was using it for the first time and thankfully my husband figured it out quickly.
