The bracket is very stable and easy to use. The alignment can be adjusted individually to fast two joints. All buttons and ports are recessed and so continue freely accessible when the One in the bracket. The holder has a big rubber suction cup, with which you can attach the bracket without difficulty on each disc. Have the support already several days at the wheel and it is still keinn once dropped. The only thing I particularly with respect to colder temperatures in the winter, is to consider something the weak spring is generating the vacuum. Otherwise, 5 star and a strong buy recommendation for this bracket.
