The camera is very practical, ergonomic, I always in my bag that allows me to film any time. Quality side that is not too bad provided you have the light, I find that image stabilization is very bad but we still made good movies but still light years of GOPRO. The sore subject: the tightness, it was announced on the product 30m and 12m fine background water enters. Going through the various forums I realize that this is the problem of all of this camera processors. The closing valve is simply fitted with a poor seal, in addition a ring is attached to it, as if something could attach above or ensure the camera, pulling the valve just opens! So beware, I am a diver and I bought a waterproof camera to film underwater, and what is more than 30m, balance water penetrates very quickly. The information is totally false. In seeking an alternative to the high price of the GOPRO (350th for 11MP and 250 for the 5MP) saves 150 euros to say in the process, I should wait and buy a GoPro. To make small bike movies or when swimming it is appropriate, for the rest, to forget very quickly.
