I thought at first it can be a very good alternative for conventional car mounts the magnets. Was sadly disappointed. Maybe that's to use the magnets for small cell phones, not for my Sony Z1. Although the focus has been chosen precisely the construct wiggled uncomfortably strong. An operation could not think. The magnets hold good, strong and snap, but the phone also turns in the holder so you have to correct the position permanently. By and large, only a holder which does not stick, making operation in the bracket impossible. Thus, the magnets hold the smartphone only to the height, wiggle when touched and can only be operated when the phone is held in the hand. Too bad nice design, glue holds well with no residue and an attractive appearance for my purposes useless.
