I love my Sensei Ten. It's a comfortable, reliable ambidextrous mouse that works well for a mixed work/play role.
Except my wheel started jumping. I'd be scrolling through a document a mouse-wheel-click at a time, and every now and again, it'd bounce a whole screenful. Or it'd scroll in the opposite direction to that desired. Very unsatisfactory.
I surfed the information superhighway in search of an answer, and found one: the wheel's rotation is measured using a component called an "encoder", and the wheel has a hexagonal post on one side which fits into a corresponding hole on the encoder. This post is made of what looks like nylon, which wears pretty quickly, resulting in a sloppy fit. This sloppy fit is what produces the undesirable behaviour. All the fixes I saw on the interwebs involved soldering irons, and some of them altered the mouse wheel geometry so much it could affect the middle-click, so I noped out of those.
My fix was to wrap the hexagonal post in a single layer of regular sellotape. This was very fiddly to do, and you need good eyes, a steady hand, and a sharp knife to do it. Well, one out of three ain't bad, and I got there in the end.
Result: Nice solid scrolling, just like it was when it was new. Much easier than soldering, probably more long-lasting than the "insert a tiny slip of paper" fix I saw.
