I had the same problem recently with a Logitech M105 mouse: scroll wheel
was erratic, but clickers and optical tracking were fine. The problem
turned out to be a mouse full of hair and dust that interfered with the
optical sensors on the scroll wheel. Taking it apart, there's one screw
that holds the Logitech together, cleaning out the collected gunge inside
it and reassembly fixed it completely.

I've had consistently good experiences with the Logitech mice: its been
my goto brand fir at least a decade.

Or, there are plenty of that model mo56uo Dell mice on eBay for around
$US 8
