I find this mouse compared to Apple mouse disappointing for three reasons.
1. The thumbwheel does nothing and the instructions provided no advice on how to set it up.
2. In my Finder window in columns view it provides a scroll bar for all columns. This is useless to me but worse, it mens i cannot, as i used to do, click on the column line and expand the column to view the full file name. This is really retrograde.
3. i no longer have the side swipe option that was available with Apple Mouse and tremendousely useful, especially when working with ssheets.
