I was skeptical at first, some of the reviews said it felt wobbly or flimsy, etc. but it was a good price so I took a chance. I am very impressed so far! It very sturdy, in fact the flexible arm is very sturdy & strong feeling, once you put it in position, it STAYS there. The suction cup is great, really locks into pace easily. The mounting unit comes off easily and can be rotated fully, very very handy. I am using it with my iphone, at first I had it mounted to the windshield but I didn't like it obstructing my view. Now I have it mounted literally on the clear plastic screen that covers my instrumental panel. I have it off to the right side so it doesn't cover anything & the iphone sticks up just to the right of my steering wheel but not higher than the actual dashboard so it doesn't distract.
