Design
Its most distinguishable feature is its size. It’s larger than normal conventional notebook mice and just a tad smaller than desktop mice. Nevertheless it is still comfortable and going for a smaller mouse would be impractical, as our palms are better suited to grip a normal sized mouse better. It comes with a good looking dual tone body. The sides and the scroll wheel are made of rubber to assist in a better grip. The receiver snugly fits into the back without protruding, unlike its Microsoft counterpart—the MS 3000. The problem with the MS 3000 is that with the receiver protruding out it stands a greater chance of accidentaly coming off while traveling and hence turning on the mouse. Both the mice have this nifty feature wherein the mouse turns off when the receiver is inserted into its back, thus conserving precious battery life.

Installation
Installation is pretty simple, but opening up the battery cover will require you to look at the manual.
The receiver completely fits into the body
After that its pretty straightforward and the manual covers everything. It’s a little difficult to remove to receiver when embedded in the mouse and nails come in handy. We would have liked the grip to be more pronounced on the receiver for easy removal, more so, since you would be doing it on a regular basis. Logitech requires you to install the software to utilize all the features of mouse (the mouse works fine even without the software), in particular the zoom feature wherein you can use to scroll wheel to zoom into documents. The scroll wheel also tilts horizontally to scroll sideways. It works for all the platforms which include Windows and Macintosh. For Windows 98 you would need to install USB drivers download-able from Logitech’s website.
I have been using this mouse for about 4-5 months now and I am happy that I invested my money in it. It's a great product
