ok., I've just received this after waiting over a week (not good it you need an emergency keyboard quickly).
Anway, I haven't test it, I have tried, instead I've put it straight into the box so that I can send it back ....
Well, the description says 'compact'. If you are looking for something small, light and graceful that could be useful for travelling DON'T get this keyboard. It may work well and do exactly what a keyboard is supposed to do, but I'm afraid, compact is the worst description that it could possibly be given. IT IS NOT SMALL!!!!
