Have used this housing with Lumix camera for 2 scuba diving holidays, and on multiple dives down to 40 metres maximum so far. The camera sits tightly in the housing, and the buttons are well sited and easy to use. The right hand side of the case sits easily in the hand, and the lanyard that comes with it clips to the BCD nicely. Waterproofing requires cleaning the seal, and greasing with silicon grease, essential precautions, but easily done with the materials supplied. The housing comes with a spare seal I have noy yet needed. As the Lumix has a pressure cut off that disables the camera if no housing is used at around 15-18 metres (yes I found that out the hard way) this housing is recommended. Video and stills come out well bearing in mind this is a compact, and give the recreational diver good quality pictures at depth, and an excellent and easy way forward before launching into more expensive and hi-tec camera kit if that is what you want as you progress. I have seen a number of other divers using similar kit, and heard other positive comments. Make sure the condensation gel crystals are used to prevent fogging of the lens area inside the housing, it does make a difference. Yes it does cost some money, but it has proved to be well worth it, and I have excellent video and stills to remember my dives with.
