message to those who do not like its ergonomics

Initially, I was not really convinced by ergonomics. The hard edges of this mouse were hurting the fingers, scrolling seemed too sensitive and unwanted, the click was a little hard. Until one day I realized that we should not hold this mouse as a standard mouse type found on the PC in general, with two clearly defined buttons, but to do as with the old single-button mouse from Apple. There is, likewise, a click button on the Magic Mouse, in fact it should rest frankly index, middle and ring finger on the surface, the manipulation of the mouse becomes surprisingly easy, and the click, easy. To right click, remove the index and middle finger and use only the ring finger, the touch surface now interprets the click (software and not mechanically) as a right click.
In short, to love this mouse (for me, I love it), you have to give time to adapt, and not want to impose the usual PC mouse.

Other points of satisfaction:
-at rest, the mouse consumes virtually no, no need to turn it off, the gain would be negligible
-The mouse is always instantly operational, whereas with other bluetooth mouse (Microsoft and Logitech), there was a time to "wake up" a bit annoying
-esthétiquement, it is very successful (and robust)
-the scrolling (scrolling) is a marvel on web pages
