One positive point: the sucker works very well. Cons: 1) The telescopic arm is certainly adjustable but as soon as we open the safe door, the arm moves and lose your orientation setting. And to readjust it's very long and tedious. 2) The very narrow mirror and its curved shape reduces reflection significantly baby. Despite the telescopic arm, the mirror is very far from the driver (and I have a small car, compact). In conclusion, it is quasiement see anything and in addition it must be viewed mirror each use, 2 people. Product unfortunately poorly designed.
