[EX Q]: This was exactly what i wanted, perfect size.
[EX A]: Good Review

[EX Q]: Wonderful music from first track right through to last.
[EX A]: Good Review

[EX Q]: The product was supposed to be wireless but I can only use the keyboard in complete darkness. It takes two AAA's, which is very annoying. As much as I'm paying for this keyboard, it should at least have Bluetooth. Not a bad product, just not exactly what I needed. My new Dell laptop now has Bluetooth, so hopefully I'll find a use to this.
[EX A]:
