Camera with quirks

I have informed me in advance and find out that there often problems with the on / off button was because the pin of the underwater housing is too long. Therefore, I have asked explicitly by the manufacturer (Satchef). According to the statement, this error was "resolved long" already. So I bought the camera (set incl. Remote control) with a clear conscience, but realized after 1-2 weeks a little more intensive use, that the on / off button was broken (pressed). The camera can be turned on even though a remote control, this is however not waterproof, ie underwater photos were no longer possible (unless you make every 5-10 seconds a photo so that the camera does not turn off).

Otherwise, the camera will take but a good impression. The pictures are good and the colors also. The permanent Fisheye is a matter of taste, I personally think it is much better, because the recordings cover a wider angle. Only when shooting video it can be a bit confusing. What is even more striking are the right stiff buttons. In addition, the housing must be reamed to make the camera GoPro accessories compatible. The integrated screen is class (at GoPro you have these so expensive to acquire).

Of course I returned the camera due to the defect. Satchef claims to have tested all the cameras on the button problem. I doubt, however strong. The HD Pro 2 I will buy for this reason not again.
Should the camera be reworked, the HD Pro 3, however, could be a top camera. This would require, however, the button housing problem be eliminated, the knobs should be a little smoother to press and the underwater housing should innately have a larger bore (in order GoPro accessories). Class would be if one could distinguish between normal and Fish-Eye mode.
