I had bought the housing as an inexpensive alternative to the official version of 200 and in principle it works quite well. It holds tight, the camera (Canon HS 220) can be switched on and off in the housing and naturally trigger. At all other settings of course you can not ran, but I did not expect. There have been problems only when we went so really dive. Thanks to the pressure underwater, the housing bulges (even with only one meter of water!) On the lens and the place is no longer enough to extend the lens. The camera simply ended only with "Lens Error" and that's it. This means that more photos can not even snorkel fire, let alone while diving. It is sufficient degree so as splash protection while kayaking, but here the housing fogged then fairly quickly from the inside ...
