I wanted to have a mount yourself kit for my Galaxy S II. Because the video quality in full HD is at high-end smartphones now on the quality of a camcorder 100 to 150 Euro price class, apart from the zoom times. The plastic molded part, which slides in a kind of rail and is pulled back by a spring, initially stuck slightly. But after about 20 times slightly tilted back and forth has become the self-correcting. Better as a shaky game, that would be unrecoverable! The supplied tripod should be regarded as nice little bonus, but only in an emergency pull into consideration. I have a solid tripod with quick release plate and ball head. There I have the bracket mounted and am very pleased with how quickly I mounted on the smart phone and have lost again.
Be careful when screwing on the Tripod! Do not tilt, because it is a relatively soft plastic, so that the thread of the bracket can be easily damaged.
For the price ... this my first intended tinkering would not have been worth the time spent. I am pleased with this support and the successful purchase!
