Excerpt: This is a good mouse but it is too big for a laptop. I thought it would be smaller as I was searching for a notebook mouse and this one came up on the search. Also, the cord is way, way too long and it gets in the way. This mouse is more appropriate for a desktop computer.
Excerpt: Easy to use, ample cord length, can be used on different laptops by attaching to any available port. I prefer it to a wireless Mouse - no interruption due to "unseen glitches" in connections. Best buy at the best price!
Summary: It was working well for 6 months. Now, as other reviewers had mentioned, the left mouse button behaves erratically. When I click on the left mouse button, it sometimes double clicks at random. It looks like a problem with the sensor. You get what you pay for.
