Review on Gopro Waterproof Telescopic Pole - Extend Your Reach with the Number-one Transparent Floating Hand Grip and Selfie Stick for GoPro Hero 6/5/4/3 AKASO YI 4K Action Camera by Nadia Miller

I bought it specifically for underwater use as I needed a handle that also works as a float. The buoyancy comes only from the air in the grip, but the grip lets that air through. During the dive, the handle was about half full of water. As for the camera, there is no functional way to get this water out, making it pretty much useless to me.
