Title: You get what you pary for.
Review: I bought this mouse for a back up to the Microsoft Blue Optical mouse which has unfortunately been discontinued. I had used the Optical Blue mouse for years will little complaint except that I simply wore them out. After three months of use, the wheel on this mouse started being glitchy, in effect it would scroll on it's own. I was getting these "jerky" continued scrolls afterI would stop. Sometimes, I wouldn't even be scrolling and the screen would simply jerk. I suspected the mouse and plugged in another and realized the new mouse "clicked" when I used the wheel, in other words, the scroll wheel on the first mouse, like a gear, was basically stripped out and would continue to scroll regardless that I had stopped. After only a week of use, I noticed this mouse starting to do the same as the first. Accordingly, you get what you pay for. I have become increasingly dissatisfied with Mircosoft's products. If it aint broke--don't fix it.
