I haven't tried it in water, I bought it for protection against dirt and rocks. Excellent value for money and good quality

Used for 2 summers for spearfishing, up to 40 meters depth and everything was fine, but the day before yesterday, during a dive at 34 meters, it cracked diagonally in front of the lens. I didn't realize it until I came out of the water. The moment of the crack is visible in the video and it is indeed due to the pressure at 34 meters - luckily it only took in a little water and so far the GoPro 9 has survived, but I will now buy a different brand. When I bought it, it said on its website that it is waterproof up to 60 meters, but apparently that has been removed now

It arrived within a day, the plastic, although I read the comments, seemed quite good for its price. I tried it on the Hero 9 Black and it fit perfectly without any unnecessary gaps. I tested it briefly in water (not in deep water) and I didn't see anything getting inside. It seemed to fit quite well, but time will tell. So far, I am satisfied with the money I spent and the quality I received.

It's a great case! Good value for money. I tested it in water a bit and so far, it has already proven to be worth the 14€ I paid for it. If you really want something of higher quality, go for the 40-50€ range

The quality is mediocre, the latch is made of such soft plastic that when you try to close or open it, it gives you the feeling that it will break
