Query: Awesome mouse!

I purchased this mouse for my MacBook I recently bought and I couldn't be more happier with it. It's very comfortable and responsive. I just took it out the package, inserted the included batteries, plugged in the USB receiver, and was using it in seconds! I also like the feature of sliding the USB receiver onto the base of the mouse when I'm not using it since it activates a switch that turns the mouse off to preserve battery life. This also makes it very efficient for traveling since I don't have to hunt for the mouse and the USB receiver separately - they're hooked together. Very nice! Also, when I remove the USB receiver...the mouse automatically comes on & is ready for use.So, I highly recommend this peripheral if you're looking for a portable mouse for your notebook.
