I opted for this mount, as they may not be as high attach through the pre-formed arm, as with the thick arm and looks more elegant. It had to be a universal mount, because my phone plugged in Flipcase and we want it to stay tuned. So cover behind fold and clamp. This works great and the keys are also not covered. Unfortunately, a weak point is built into the arm, which make the phone vibrate strongly in the lightest road bumps. Result: for example, the street names in the Naviapp or song title in the player is no longer leesbar and you always long to mobile to keep it quiet. It's frustrating. The vulnerability is not quite the graceful arm, but the transition from arm to hold in my observation. This consists of only two thin filaments that run around the clamp wheel and in a sense are indeed stable since the two support arms by their distance, unfortunately, not at all and let in the other perpendicular to vibrate the phone. At least keep the whole quite well even in bright sunlight. Also, the ball joint is not pretending. A small point of criticism are still sometimes clattering feathers for the opening force of the jaws begin to vibrate the inside of the retaining plate.
Otherwise, I would say, the holder is suitable for all mobile phones to the Galaxy S4, as regards the weight. One just needs to make sure that the phone which is to be held, there is no key in the jaws has.
01.12.213 supplement: In my review I got immediately a new holder of HandyNow sent. One would have an improved version, was in the package insert. Externally, I could not notice any changes. Since the Probelm constructive nature (two bridges to the pinch wheel, which can not be stiff enough), has not changed the vibration. For precisely the setting is easy, but that makes you stop only once. An improvement can I tell when spring rattle that is now in the compressed state (with or without a mobile phone) does not occur and less in arms relaxed. You have to push together with an empty mount up again and then you have no rattling arms. Then I give now four times star. Otherwise, I'm still happy with the support and have to say that it probably is relative to many other offerings, especially in price / performance, the better choice. The service of HandyNow is certainly hard to beat. Thanks!
