Excerpt: I bought this for my mom. It was hard to have your hand on the mouse and left click. My fingers automatically lined up for the right click. As my mom used this mouse, the cursor started jumping instead of moving smoothly.
Summary: Hardware wise this mouse is ok for the price, just the right size for a desktop and no buttons on the side which I hate. The negative is that this mouse has an inherent scrolling issue, in my case the mouse would loose focus while using a scrollbar, I have just located the issue to a program called ipoint.exe, when this process is disabled the mouse works fine.
