Superb quality with everything you'll ever likely to need for installing. Although mine doesn't quite sit square I haven't yet investigated to see if I can alter it.
Not a biggy. Still the best phone mount available.
As I've come to expect with Evotech Performance items these are very well-made, fit perfectly & are great value for money. You always know you're getting quality from them & that when you receive the parts, they'll fit properly without having to 'work them in'.
