Excerpt: I have always preferred to use a mouse, but was never convinced that a Wireless Mouse would work for me. I finally decided to go wireless and all I can say is, "I should have purchased this item years ago!" It worked correctly right out of the box.
Summary: My Microsoft mouse started to have issues with the rubber portion of the rolling wheel so I upgraded. The first wireless I purchased mouse was way too small to use for any amount of time. My hand cramped after about 15 minutes.
Summary: Got this mouse for my laptop just because I was tired of using the touchpad. I'm glad I did. This mouse is great! Very smooth, responsive and I'm gonna sure give the 2-year battery life span it claims. And being wireless is a big plus. You will not regret getting this mouse.
Summary: I've only had it about a week or so, but the Logitech M510 is flawless so far. The laser is invisible, so I guess it's infrared (possibly making it more energy efficient) and it tracks perfectly.
