We tested the underwater housing and are very satisfied. Easy to use, easy operation under water great result of photos. So far we have tested the case only in the lake up to 7m, but we fly to Mexico to dive and then we test the case also to about 30 - 40 m. But we are very confident, so far we have never had such a good case and of course the camera to. Man, the housing and the Canon PowerShot SX220 HS Digital Camera (12MP, 14x opt. Zoom, 7.6 cm (3 inch) display, Full HD image stabilized) Share gray really.
