The magnet is quite strong, the store will be very fast, I bought it in order to not always aufpfrimeln the cable cover must, because I fear that at some point suffer the absolutely necessary for me waterproofness.
I use it only in the car and home,'ll probably have to buy a second, so one can always be in the car.
Clear you have to take care, that the mobile terminal and just lie, because otherwise no charging takes place, but hey, that's logical because just magnetic and no plug-in connection.
The magnet I find quite strong, which does not fall off on its own and I can phone even lift it.
I würds buy again.
