Got this setup for my birthday. It consists of 3 separate part numbers. The base has a stainless U Bolt and the 1in ball (I put a wrap of electrical tape so I wouldn't mark the bars). I have the shortest "neck" they have, and the large XGrip to fit my Samsung Galaxy Note2. To round out the install I picked up a 12V socket with 2 USB outlets and a USB to mini USB cable to charge while I ride. This thing is very solid while riding, and I can get a variety of placements/angles to suit. Good quality
I installed one of these, and while I installed the RAM ball mirror mount (on the front brake master cylinder mirror mount, covered by a black vinyl cap for UV protection when not in use), I used the provided arm with the power port thru-bolt on the RAM 8mm handle bar riser bolt mount.
