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.

Perfect solution for multitasking and multi device
I'm a multitasking person and juggle sometimes between two devices. This bud is a great tool that I needed to be able to jump from one device to another without worrying about adjusting the Bluetooth. I'm comfortable with it and the sound is better than expected. It does the job and doesn't hurt my ear. Long lasting battery life.

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.

Not bad for the price
Great white noise option. The other nature noises seem off. Also, the light coming off the on button is bright and even after covering it, you can still see the light.
