Easily the most useful iphone accessory I've purchased. And the part that holds the phone is perfect, it's not clunky and overly large like other mounts you see.

The "dots" are a great idea. I have all three installed in various spots around my dash, and just move the mount around depending on what I need. The mount can be tightened to where it's 100% stiff and will NOT budge at all, and with the slick built in tool, can be adjusted to whatever you want.
Plus, it makes for a really good desktop stand with the suction cup (which is also one of the best-designed suction cups I've seen).
Coming from somebody who spent $100+ on various solutions, I HAVE to recommend this mount.
