Summary: I have tried a ton of mouses. Now the photo makes it look like it has a cool blue glow . . .it doesn't. So that was a bummer, but the feel of the mouse is sooo smooth and it literally does work on any surface. I don't like logitec mice because they don't seem all that compatible with windows, but this mouse is smooth and since I do game especially stuff like "bejeweled" when you need a fast mouse, I highly recommend this mouse. And best of all, it's silent.
Summary: I converted all three of my computers over to this mouse. With all of the function selections you can make, it is an eight-function mouse with all of the selections easily programmable. My only criticism is that the buttons on the upper part of the sides are a bit difficult to engage since you have to also change your hand position to steady the mouse in order to engage the upper buttons. I still give it my five star rating with easily accepted features.
Summary: I had one of these before in red. When my old one finally died out after many years I was happy to see these were still available. The pink is very cute for someone who loves pink. Features the side buttons to go back and forth among pages and a scroll button to easily go down a page both feature you don't know you miss until you some how buy a mouse without it and it drives you a little crazy.
Summary: Ordered this mouse because I love the color and the fact that it's the Blue Track Technology. I finally got my new laptop and got to use it today and it is so smooth! I love that the wheel doesn't "click" when I'm scrolling. The scrolling is so smooth and flawless. Not choppy at all. Perfect mouse at an amazing price!
