This mouse is a decent weight and seems well made. I really like the thumb rest on the side of the mouse as it was never a problem for me and just made it more comfortable. I also like how the mouse goes to sleep after about a minuet to save battery. Sometimes simply moving the mouse will wake it up, and sometimes pressing a key will do the trick. The software for this product is pretty cool as it has all sorts of color swatches and you can even go into the color chart and choose or create a new color if you want! You can also turn off the colors entirely and the program will show you the charge level if you want to know. I've only been using the mouse for a week, but I'm very happy with the price.
