Conclusion: The Logitech V500 Cordless Notebook Mouse has a scroll panel instead of a wheel, so you can scroll from side to side or up and down just by sliding a finger. We like that the USB RF receiver stows inside the mouse when not in use and that customization software is included, but the mouse isn't all that comfortable to hold.
Pros: Has a four-way touch-sensitive scroll panel instead of a wheel. Works wirelessly with a 2.4-GHz RF connection. Receiver stores inside mouse when not in use. Mouse folds flat for easy carrying and turns off automatically when folded shut. Includes a soft carrying case and customization software. Powered by two included triple-A batteries.
Cons: Raised design isn't comfortable, since it doesn't rise up far enough to rest the hand on. No way to tell when batteries are running low.
