maybe the holder could have been a little more delicate. This is a huge part. Specifically, the recording for mobile phone: it finds in safe place and is also held great, but it is not possible to insert my S3 center without pressing the volume control. So the phone is not small between the jaws looks lost something. The holder protrude excessively far forward on the display. One could clamp three devices one above the other. What is thought, no idea. Very positively makes the mammoth suction noticeable. Once sucked could hang up, a 10 kg dumbbell in mind. Conclusion: functional, but striking.
