Excellent brand-name replacement mouse for older PS/2 computers
These are great roller ball mice to replace worn out ones for older "legacy" computers. The newer optical mice often are overly-sensitive and difficult to down-adjust cursor movement speed as compared to the original equipment roller ball mice. These offer just the right amount of control over the mouse.
I purchased the mouse for an old computer that I'm playing around with as a hobby, and it's working very nicely! It's in brand-new condition too, which is surprising for the age of this mouse. Very nice!
