Friday I (finally) got my new Evoluent mouse. My first impressions are that it's NOT easy to use (or at least that it takes getting used to) and that the scroll wheel sucks. Feels like the ones I used to use 6 years ago.
The main issue (for me) however is that it has an indentation for the thumb, where the thumb is supposed to rest. This makes the upper part of the mouse fairly thin, so the space between the fingers and the thumb is thin. After using it for a few hours, my thumb hurts. I wish it was wider.
I think I will order now a
Logitech G9x Laser Mouse mainly just because it comes with interchangeable grips and one of them is WIDE. I have big hands and if I must bring my thumb in, it starts to hurt...
I will admit that it clearly will take time to adjust to a sideways orientation, but I think that even if I could adjust, it's still too thin for me.
