Very good mouse

I have purchased a total of 4 of these over the past couple of years. One I gave away with a laptop. One I wore out, the left key click became erratic. It likely was still within warrantee, but it was not worth the effort to find the receipt and return. Three out of the four have worked without a hitch. I like the good battery life and that there is a convenient switch to turn the mouse off. The small USB dongle is great in that it can be left plugged into a laptop which is all I use this type of mouse for. For desktop I use a Logitech Marathon mouse which seems slightly more comfortable on a hard surface and is a little larger and hand filling. The MX works very nice on soft surfaces, like on the couch surface next to me. The MX is very forgiving as regards the surface, even working on a glass table top. But I have noted of the 4 I have used, one was a little iffy on glass, and that is the same one that developed the left button issue. I also like the mouse comes with a zippered case...very useful for travel. Another plus is the MX mouse wheel can be switched from free spin to detent just by pressing on it. It makes is easy to go from fast scrolling to slow. Logitech also has software to make the dongle pair with other Logitech devices such as a keyboard. I have not tried it but different types of mice could be added, such as a trackball. My recommendation...when I need another portable mouse, I will look to buy another one of these.Read full review
