La Teva Strata Universal 44. If you want THE keyboard, this one will most likely do it for you. It works for my phone in both directions perfectly! Their little feet grow so fast! Columbia usually has the best arch support Good quality product that will last years to come! Highly recommend this cutie. Although the tools that came with it are not very sufficient for me and I like to use my own for a quicker install/tear down of the rack. But I wish Id known how much theyd wear in; I originally got my usual size, and the straps were so tight I really could barely get them on. Hoping they will replace.
