Query: The mouse that couldn't

Don't waste your money, the product is still in its infancy. It is made of cheap plastic, batteries (which it consumes faster than cheese) are hard to replace.The response of the mouse is poor and lags as you move it around. It doesn't know how to accelerate properly. And if the signal goes out of sync with the base unit you can expect frustration getting them to talk to each other. Stick to a wired optical mouse.
