I took this plastic wonder into the ocean every day for 6 weeks. I put my pos samsung camera and a gps in there. surprisingly they both fit. It did the job of keeping the water out between 0~15m of water.
-1 star because on the last week it started to get condensation in the inside. I did not know how to deal with it and now there are salt linings in the bag making it kinda blurry.
Also the lens part of the bag. I dont know if its not supposed to come off but when I tried to clean/dry the bag it wouldnt come off for some reason.
