I have already bought in the past much more expensive car that supports it. I was never satisfied because it is moving all the time or it was very inconvenient to use. I was especially attracted by the price of one. Well I'm not disappointed. It is the support car I've ever bought. The suction cup is very effective and sufficiently rigid arm to securely hold the phone in place. I also tried the attachment for air vent and it works very well with this simple and universal system. Best of all you can even customize the support with a photo insert under the little window! 5/5 I recommend!
