optical mice

This mouse is perfectly great. Like the other have said, it is accurate, easy to maneuver (great for gamers), and battery conserving. It automatically switches to conserving mode when you do not use it for some time (like screensaver of the monitor), it blinks instead of continuous emitting light. In case, you want to conserve even more energy, plug the receiver back and it would be turned off.

The in-the-mouse receiver is an innovative design. Absolutely great for all those who use laptops. People who use desktop would also love the idea of turning off the mouse while keeping the receiver ready in place in case you need to dash out of the house.

I have a desktop and a laptop and all what I have to do is to plug in the receiver. When I finish just turn it off and in the morning I am ready to go again.

About the battery, it is true that all wireless optical mice consume lots of batteries. However, a charger would solve the problem nicely. Make sure you have 4 AAA batteries so that when you charge 2 you have 2 other to use.

This mouse is awsome. The dpi is good....battery life is great and you don't misplace the receiver when traveling; because it GOES INSIDE THE MOUSE.

Ben (one of the reviewers). You put the wireless receiver inside the mouse to turn it off.

Anyway...good mouse for traveling

Nice mouse with a compact reciever and a clever design for storing it inside the mouse. But it burns through batteries. Even taking them out at night, only got ~10 days use. And no off switch!
