I purchased this for use as an external mouse when I got my new laptop with built-in Bluetooth (a Dell Vostro 1500). There are many things I like about this rodent:

1) Since I'm left handed, I want a symmetrical mouse, one whose shape is not formed for the right hand. This mouse qualifies (unlike a lot of Logitech mice).
2) Although it is on the smaller side, it still feels comfortable in my large hand. I have hands that can easily palm a basketball, so many travel mice are unusable for me because they're too darned small!
3) Laser precision, and no annoying red light. Nuff said.
4) An on/off switch on the underside so you can turn it off, throw it in the laptop bag, and not have to worry about it bumping up against something, clicking, and waking up the laptop. This also helps conserve the batteries (see #5 below).
5) It's pretty miserly with battery usage. I've had this mouse about six weeks as I write this review, using it an average of about two hours a day, and I'm still on the original Duracells that came in the package.

If you want to use the side scrolling features of this mouse, you'll have to install LogiTech's SetPoint software. All basic mouse functions can otherwise be handled by the Windows default drivers.

Overall, this is a good product. I wouldn't have this mouse on my primary gaming rig, but that's not what it's designed for. It's designed for the way I'm using it...as an alternative to the trackpad on my laptop.
