Very pleasant to handle

This mouse is especially nice in hand. Fine, she resolutely turns back to multiple buttons monsters. Despite this, the wrist does not feel fatigue as may be the case with the mouse gem Apple offers (that has at least as many features as the monsters ... without a single visible button !!!!).
Its micro-switches are gracefully hidden under its hood whose perfectly designed flexibility allows their solicitation.
Selecting 800 dpi / 1600 dpi is very useful when working on the undue drawing or other apps claiming a scoring finesse and precision is very nice.
A small criticism, however: you can not do a lot of functionality settings. Certainly the Mac interface allows adapting the speed of movement or click, etc., it can be used for left or right handed, the two "buttons" main (click and ctrl-click) that can be swapped. But, to my knowledge, the features are predefined and especially the click wheel that works in ON / OFF to scroll a window without having to turn the dial can certainly be very useful for some, but personally, I ' would have liked to associate a different function (double click or click cmd, etc).
But one thing is sure, I am very satisfied with this purchase.
