I'm really surprised by its efficiency and quality for such a price!
I use it for my laptop 4.3 ". Other sizes will also go.
Moss on the sides, behind and below the telephone avoid eating too much vibration from the road. In addition to the arm / rod which also minimizes vibrations received, unlike other similar products that do not have arms so.
The suction cup has fallen only once, the first time I laid and rolled with. Then I re-attached and no problems.
There behind the phone (hidden on the photo presentation so), a small transparent cover with a picture behind (a blonde with glasses who we ";)"), nice when you did not place the GPS, we can put any picture, of course, small format.
The side edges are set very easily.
There are other gadgets come with, genre support, but I have not looked further its usefulness because the default configuration suited me very well.
Without hesitation, you can buy!
