Both are optical. Both have 4 buttons.
???
I tend to believe Knsington is better quality. True?
Does eiter one have a fifth button on the scroll wheel? I think not. True?
The Logitech has buttons on top, the Kensington on the side. Myguess is that top buttons are better. True?
Would love any input.
Thanks!
