So I was very surprised when I got the hands. The quality is top notch: the materials used are solid and non-slip coating is placed on the entire "clip" that holds the phone / tablet.
More used to put the suction cup on my windshield, I was very skeptical of the idea to install everything on my dashboard. Oddly, it fits perfectly! And unlike laying on a glass surface, it leaves no trace withdrawal.
Finally, the assembly is extremely simple to use, whether for installation or removal, as well as for inserting your phone (whatever its size). A ball allows a rotation of the "clamp" to best position your device.
