I had 3 smartphone mounts that I wanted to mount on the dashboard, but not up to my expectations. The actual bracket and the suction cup held in any case and if at all, then it dropped at the slightest stress. When I unpacked them, but came to an immediate positive feeling. The holder is small, looks good and keeps "bomb-proof". As yet no other intended for the dashboard and windshield mount could be fasten on the stick-on sheet metal plate, here is no tin plate and the bracket is pressed directly onto the dashboard and pressed a lever. As my living room table has a similar, non-returnable bottles smooth like a dashboard, I tried it right here. The suction cup feels sticky or it is and what a surprise, the holder sat "bomb-proof" and I had trouble getting it removed from the tabletop, but succeeded with a little patience and without any adhesive residue. Since I have a Lumia 830, but it must be clamped exactly in great Verstellweite so that the on / off switch and the camera shutter button is not pressed. I can only recommend to anyone who wishes to use his smartphone on the dashboard, to opt for this bracket.
