Microsoft brand but ...

The purpose of my purchase was a mouse for my laptop, and being small enough for flat tucked into my bag, not just for a "big ball" exceeds one side of the bag ^^
And then my second criterion was either wired it to avoid getting stranded stack when I use it ^^
The pros:
- Level Ergonomics, no worries, it is flat and fits perfectly into a bag.
- Technology "BlueTrack" which allows using the mouse on different surfaces, on that there is no problem, the promise is kept.
- And of course ... the price was really attractive (about 11)
- The thread is long enough to make the computer tower (if the USB sockets are located on the left) to use it safely

The -:
- This is a moment that I use and what I find .... dextrêmement annoying is the fact that the hull top (the white part above the colored outline) is not fixed ... suddenly, there is all the time the game between your hand and the mouse, in summary, you really grasp the mouse with your hand to good grasp. For a Microsoft mouse, I am disappointed that detail that spoils everything.
- The mouse has hyper sensitive buttons ... you have all the time to be careful not to let her fingers lay too heavily on the mouse at the risk of making bad clicks ^^
- It's clean ... but the seller when I received my mouse, the package was really dirty, slightly damaged, pieces of labels that have been glued and then torn off.

Finally, the look is cool and unusual, despite the hull above who wanders a bit where it wants, the whole is not bad but I would not recommend it.
