When I unpacked the clock, I was struck by its size. 16cm Diameter, so no small alarm. What surprised me positively, is the quiet pace. No clacking noise nerve. The four large suction cups I was skeptical as to whether they would hold at all. But until now they hold the clock on the tiles sovereign. Of course, the tiles should be free of grease and clean previously. Alternatively it is also a stand supplied with it. So far I am satisfied with this product. And at the time of 13.25 Euro to do probably nothing wrong.
