I'd describe myself as a track pad kinda girl, having had bad experiences years ago keeping the ball clean on the original PC mice, and more bad experiences with connectivity and battery life on first generation wireless mice.
My current HP Envy has a very unresponsive track pad what ever settings are chosen, so a mouse seemed worth a try to see if was any better. I am seriously impressed with the mouse.!
It was easy to install plug in a small adapter/dongle(?) into a USB port. PCs running Windows 7 and 8 found the driver and installed in in less than a minute, and then you were off, no need to reboot to get it to work.
The mouse is medium size, I've seen bigger full size mice, but its too big to be described as a travel mouse. Its fine for my medium sized hands but guys with big hands might prefer some thing a little larger. The mouse is sensitive, only a small movement needed for it to glide across the screen. It worked well on a smooth table and on a textured sofa cover. It is built in a symmetrical way, although the buttons on the side are designed for right hand use. As a leftie I've adapted to sub optimal design and like other handed devices found the mouse ok to use.
The product is especially recommended for PC users with Windows 8 and no touch screen. Even having a pc with a touch screen I still cant recall all of the Windows 8 swipes and clicks. (I attribute this not to increasing age but overload by having to use so many similar but different devices PC, Mac, tablets, smart phones all running different versions of operating systems) So I really like the button the top of the mouse which brings up the charms (the list of stuff on the right hand side of the Windows screen) and the button to go the desk top, where many of my software short cuts are placed, and another button to bring up the start menu. The tracker wheel scrolls, and the left and right click do the normal left and right click stuff. Marvellous.
Using the mouse with windows 7 the button on the top fans open windows a little like a stack of cards, and then the side buttons bring up the desk top and start menu as with Windows 8.
The mouse comes with a preinstalled battery and can be turned off to save power. I forget to do this most of the time and after nearly a month of use the battery is still good.
