I use this as a spare for my white Macbook. It matches well in terms of color, but I don't really care - some people do. My main mouse is a Logitech V270 Bluetooth in addition to using the built in touchpad.

As a mouse in terms of tracking, responsiveness, and the ability to do "something" when you push a button, it functions as it should. The little trackball scroll "thing" works pretty well, but it gets dirty fairly easily so you need to clean it.

As long as you use the mouse for single-click only it works fine, but a major gripe is that although you can configure it to function as a double click, you need to have your finger on the "left click" while clicking on the "right click" in order for it to work. That sounds simple, except that it doesn't always work as you'd expect it to. The side buttons are awkward and often difficult to active. You really have to squeeze the mouse for it to function.

It's not really a bad mouse in itself, but probably not worth the full retail price people are paying from them. I bought mine from someone who absolutely hated it, for much less than the $50 these things go for, so I'm not one to complain.
