The suction cup holds surprisingly well on my pretty rough dashboard.
The side bracket are made of rubberized metal and are compressed by springs.
By sprung headband can easily be up slightly over 80mm insert phones with a width of 55mm.
The lower bracket are made of rubberized metal.
The bracket is connected to a fixable ball joint with the foot and can be adjusted in a fairly wide range of angles, therefore.
An iPhone 5 is securely held. So far there has been no crash.
If you want to have something to laugh about, should take a look (in the fortunately unnecessary) throw manual. :-)
The mobile phone holder makes a high quality impression. I can only recommend it.
