I have owned this NexxTech Wireless Keyboard and Mouse for quite some time now (almost 6 years). They are still going strong. I got this on black friday at a very affordable price. I really like the keyboard. It is big and the keys are very comfortable to type with. There's also a keyboard rest pad included. The keyboard uses two AA batteries and the mouse uses 2 AAA batteries. The wireless receiver is a small square box that you connect to your computer's usb port. It might take a while for you to link up the connection between the keyboard/mouse to the receiver, because the instructions on the manual is quite confusing. The mouse is not so responsive to movements and clicks. Sometimes, I feel that there is a fraction of a second delay on my on-screen mouse movements. The one thing I don't like about the keyboard is that there are no light indicators to tell you when the caps key or the numbers key are on. The batteries on the keyboard last a couple of years while the batteries on the mouse last a couple of months.
