I really like this combined device. I bought the 360-Degree Rotation ring, but this one comes with the holder and anti- magentic wipe . It is very easy to install in my car and take not so much space. The suction is storong and the holder is sturdy which easily hold my S7 edge. And the best thing is I don't need to add another device to my phone but only just use the holder for the convience.
