Monika, for the price (~$25) my bag was great. I cut some foam to fit around the lens on my RX100 to keep the lens back from hitting the plastic, and a couple other pieces below and to the side to try to keep it centered, although I still had to work on that a bit when shooting. Big problem was glare on the plastic such that I had a very hard time seeing the LCD on sunny days so I was just pointing the best I could and hoping (many misses - thank god for digital, and the turtles that always hang around near our condo so I could visit every day). I also see a lot of distortion/softness on the edges of the plexiglass lens cover. Not a pro rig by any measure but a good intro for a casual snorkeler like me.
