Query: Not a suitable keyboard replacement

I bought this keyboard in the hopes of having a fancy roll-up keyboard to use with our Dell Mini laptop. The Dell's keyboard on the device is very tiny so a full size keyboard would be a welcome addition, especially one that rolls up for travel.The concept is great, but this keyboard is executed poorly. The keys are far to difficult to press and, as a touch typist, there were excessive mistakes made as a result of keys not triggering. Additionally, the backspace key is in the WRONG PLACE and is too far too reach. I don't know what they were thinking on this front.I am returning the keyboard.
