Support strong smartphone and effective suction cup

See video on Amazon.com I bought this smartphone support mainly for comments and the description which stated "attaches to any textured surface"
Indeed, my dashboard has some roughness that make the adherence of hazardous sucker.
With this model and after testing, I can fix the set where I please, it holds well and it's tough.
The suction cup is a bit "sticky" (which should make it simpler accession), much like those soft plastic objects for children that have played as a kid (which stuck to the windows !!!)
So, it works well, once the tackiness decreased, it gently washed with a little detergent or soap is allowed to dry and above all we do not essyue, and go again for several uses. The best do not take off at all the ... :-) And it stays in place.

Smartphone investment side, no worries for me with iPhone 5S, and the little locking screw keeps all stiff at which avoids falling iphone see on a corner (not counting the possibility of going out of fashion landscape or portrait mode easily if desired).

In short, here I am with a GPS smartphone which is hair cell where I want it in front of my field of vision to the location that suits me, it delights me !!!
