Yes, it is an adjustable kickstand (you can use like a flygrip, but not recommended in this run prototype run - and even then, it was never designed to be like a flygrip unless you know how - I may show how in the future, but no pictures doing so yet)
But here is how the Add-On's will work (more of a slip-on) - available Summer 2013 - you just simply slip onto your existing kickstand, as this was intended to work on all mobile devices - color of the slip will probably be Matte Black as the one shown is from a 3D printer.
So if you buy one now for your phone, tablet, or both, later in the summer you can stand it up larger devices like tablets more upright if you just need to view it only, as the way it is now it is more angled if installed on tablets so you can type on it
