Summary: I've had this compact mouse for 18 months with absolutely no problems. It's my favorite mouse due to its compact size and responsiveness. By turning off the power switch after use, I've gotten about a year of of use from the original batteries before they needed to be replaced. The nano USB connector works fine, although I had to find out from an Internet search how to get it to override the touchpad on the laptop I primrily use it on.
Summary: I bought one of these mini usb mouse in egypt last feb for use with my netbook i have been that impressed i have now bought a second one to replace a microsoft bluetooth mouse at home, the batteries in the genius micro last for months, and are very accurate to use, they are very small and ideal for netbooks etc , and work on any surface.
Summary: This is the latest addition in my mouse family and it is being used on my better half's computer, on which I lately spend most of my on line time so a purchase of the mouse was a must - I hate "mouse pads". The one I bought is almost as in the picture Dooyoo provided with exception that top part of the mouse is blue instead of black. It is an optical wireless mouse.
Pros: optical, wireless, small, responsive, accurate, small USB receiver
Summary: What can I say but it is an excellent travel mouse to use with your laptop. Easy to install, setup and use. Basically, it's plug and play and nothing else. Like where the USB connector inserts into the mouse itself so no losing it. Would recommend this to people who are looking for a travel mouse.
