Review on TELESIN Waterproof Transparent Extendable Accessories by Thomas Mertz

Purchased for diving. The expansion aspect worked well and the stick is very light. Have I had problems with in and after water. Twice I lost a camera with a floating component when jumping off a boat. The strap attaches to the handle with a very short screw. It falls apart after about 3 turns. It was very stressful to see a brand new camera fly away twice from something that could easily be improved with a longer screw. I could have glued the tape on, but since it's impossible to get all the water out of the inside of the pieces, this was a one-time thing. The second problem is that water gets into the handle. Water seeps through the seals (no seals?) and cannot be removed. It's unsightly and likely to mold soon.
