As some reports, the plastic holder can cancel.
I have the Fliter min. 10 times up and down to abgeclipst and slight scratches (which one does not see in the video) nothing happened.
One has to ideally place the side with the ribbon to the outside and when you look at the lens, then it is important first to the right to pull the filter on the ribbon and then to allow the holder are exposed to hardly any resistance when unclip, then holds the Filter multiple dives.
The product fulfills its purpose from about 5m deep. While snorkeling you should work without a filter, otherwise you get a red tint.
The price is a bit too high, but still recommended!
