the problem is that the screw which holds the door-opener can get loose. thats why it should be fixed/treated with locktite(half-strong). the position of that door-opener must be adjusted so one can get the full image-size of 58mm lenght. mine got loose during shelf storage!
lets hope that promised digital horizon will be of topquality.
