This housing is used to protect my G12 at sea kayak outings. Product tested at several outlets in Corsica: no problems encountered so much to my expectations. consider the fact that the G12 can heat in the chamber, so turn it off after each series of shots because it can appear mist, also use a bag of protection against the sun and salt spray and under these conditions the proper operation. All features are accessible, zoom, ISO, program etc ... Not tested under water. For the rest, the closure system may seem a bit fragile, so close and open carefully. A little bulky, but it is a waterproof case. And pictures taken are excellent
