This is the best keyboard I have ever used. I've tried more expensive ones, but I find they try to pack way too many extraneous features. If you want a simple, easy-to-use wireless keyboard and mouse set, this is the one for you. Plus, it's very inexpensive online, probably between 25 and 50 dollars. In addition, the few added buttons are very useful, such as the standard Play/Pause, Stop, Fast Forward, Reverse, Volume control, etc. They work right out of the box, but can be changed by the user to better fit the user's need. Overall, it's easy to use, simple, works perfectly right out of the box, and doesn't take up too much space on my desktop. I'd say if there was one negative, it is that it uses AAA batteries, but they end up lasting a long time.
