This is the simplest, cheapest and above all the most effective I've ever had!
A foot really well attaches to the windshield, a clamp that holds virtually all laptop without taking the head-on buttons turn off because we choose where we put the claw (with rubber to avoid damaging your precious portable) and a simple articulation to put your phone in the best possible position. What are you waiting for? Me nothing!
So for less than 6, it is clearly 5 stars !!!!
