Pros: This mouse glides smooth acrossed whatever surface you put it on. I have had no issues trying to get it to work with my system. Fits well in the palm of my hand. Compared to the old Gear Head mouse I had its wonderful.
Cons: The mouse scroller doesn't click, not really a con but some people may not like it. It is slightly smaller than others.
Summary: I've been using this mouse for almost 11 months and I love it. It fits my hand great and feels nice. The dongle can go right in a slot under the battery cover, but it's so small that I don't even need to take it out anyway. I've only changed the batteries once or twice and I've used it everyday. Being able to go forward and back on pages using the scrolling wheel has been surprisingly helpful - I didn't think I would use that feature when I first got it.
Summary: I just plugged the mouse in and it works. Its a good size, has smooth scrolling, and was on sale. I also like the on/off switch. This should make the battery last a really long time. It is excellent for general PC work.
Summary: It arrived 1 day later than estimated but I like the design of it and it has great feeling of clicking, scrolling, and so on. Battery is usual AA size and it last really long. No red light from bottom part and everything works perfect! I've been using for 2 months now and still there's no problem at all! <BUT!> If you didn't bought it, you have to know that the size of this mouse might be smaller than you expected.
