Does exactly what it is supposed to do. Used it while jetskiing over the summer, and as a little handheld camera while at the beach with friends. The case adds a little bulk & weight so it makes it cumbersome for goggle mounting. Still trying to figure out a good stable solution for that because my main intention was to use it head mounted for watersports and paintball. Unless you do a lot of faceplanting, you don't really need to bother using the waterproof case for skiing/snowboarding... My friend and I used his camera for snowboarding last season without this case and had no issues at all.
Oh, and maybe I'm just dumb, but at first I thought the case wasn't compatible because I thought the magnet on the switch would mechanically move the switch on the camera as well.
So when you put the camera in the case, be sure its not on record. When ready to record slide the orange switch, and though the switch on the camera doesn't move, don't worry, it has been triggered within the camera to begin recording.
