Way back in September of 2012, I wrote a fairly lengthy review of the HoverBar by Twelve South. The device is a mounting mechanism for iPad. It is not a new contender to the mountable space, certainly not two years later, but it is a well designed product. Twelve South, a South Carolina based company, limits their product development to a low number each year, ensuring proper care is spent on each device they launch.
The HoverBar 3 is an intentional upgrade on the previous generation. The 22" arm extends from a bi-directional assembly that screws into a metal clamp. Overall, the design and assembly is almost exactly the same. Where the new generation differs is the compatibility for iPad 2nd - 4th generation, iPad Air, and both versions of iPad mini.
