Review-Shack has reviewed the Logitech MX700 Cordless Optical Mouse, here's a quote :
I would definitely recommend the Logitech MX 700. This is the first Cordless Rechargeable Mouse that lives up to its name. It performs well and has a comfortable design. This product is a great buy for gamers, casual users, as well as any of those who have been hesitant about getting a cordless mouse. At the retail price of $70, this mouse is well worth it. I'm sure this mouse will last a long time for any type of computer user. Logitech has finally proved with this mouse that cordless technology is just as good as a wired mouse.
