The bag was completely water resistant, I tested diving to a meter with the bag. An excellent purchase at a good price. The locks turn easily and the strap is good when you can adjust it yourself to a suitable length. In addition to my phone, camera and wallet, I kept other small things there that needed to stay dry. I also tested filming under water, it works, although from the other side (the darker side of the bag) it is difficult to see through the screen if it is bright outside, thus it is more difficult to hit the right spot on the screen. The bag floated completely, there is no danger of losing. I recommend.
Easy to fill and use. Not too rigid material.
