Query: easy to install. reasonable price. wish it can be more sturdy.

As a bluetooth keyboard it talks to my PC easily. I have a Viliv S5 and this keyboard is about the same size of the palmtop PC. It supplements the weakness of input of a palmtop PC. These 2 devices go together in my pockets.This meyboard is a good companion for whoever has a palmtop PC and needs to have mobile, easy keyboard inputs.
