Why?
The mouse looks great, yes! But I want to work with it (and true as I am a professional Mac users!) And not flay impression!
Their ergonomically they like it very much and is really suitable for me, because if she does !!!
And that is the reason for only 2 stars: after a short time is over the scroll ball, making a clean working absolutely impossible! While there are tips on the net, how to clean the ball, but that's just rubbish! Once across, you can forget the mouse!
Sorry, but design is not everything. Here therefore unfortunately not advise!
For off-and-on-surfers who rather play with the Mac, it's ok for serious work: Wrong!
Who knows a good alternative?
