Title: Horrible -- do not buy
Review: I am returning my unit tonight - it is not a good product. The problems include:* Range is about 6", yes inches. I have the keyboard/mouse on a keyboard tray and the transmitter sitting on the desk. It complains about having a weak signal. The keyboard also misses keystrokes because of this. I'm using the batteries supplied with the product.* Middle mouse clicks are nearly impossible. I use a browser that supports middle-mouse click to open a new window in the background. This is virtually impossible to use with this mouse. You have to try at least 5 times to get the mouse to register a middle click.* The keyboard itself is a little cramped compared to my old, wired Microsoft Natural Keyboard Elite.
