Vibratory defect frequently and annoying

As described by several other reviewers the clock often has a Virbationsdefekt, ie the button the clock at a vibration on the housing "rattles", which can sometimes sound very annoying. I had the opportunity to try out in a store several SM 2 and without exception all had this defect. Unfortunately, even the ones I finally ordered on Amazon.

Furthermore, I would still be able to overlook. Problem was at my clock also, however, that she wanted to join after a while simply no longer with my phone (Motorola Moto G). However, as I have since the - incidentally very big - had shortened metal bracelet, I had to extend it again in order to return the clock can. This cost me a total of 17 euros, which of course I do not get reimbursed. Very annoying.
