Just received this to set up my tablet while I work next to my desktop PC so these is just my initial review.*
It's extremely easy to set up and very strong, comes with 3 different mounting options (wall, desk and vehicle) and the arms can be adjusted or removed to suit your setup. I may move it around a bit which is easy to do with the clamp so I can use it in other settings- on my wheelchair or in bed or car, for example.
It adjusts to hold phones and tablets from four to eight inches vertically and even longer widths horizontally and the mount can be moved around and adjusted in a variety of ways. The clamps that hold it in do allow space for some cases, even with a thicker iPad 1 which is what I'm using.
After looking around at mounting systems, the price tag on this one is good too at 79.00 on Amazon.
*I purchased this product myself and have no relation to the company.
