Months of heavy use on a cloth pad and the feet still glide the same. That is usually the first thing to go on cheaper mice.

Precision in FPS and comfortable clicking in long strategy sessions. I did not need a second mouse for different genres.

Even when I am moving fast and gripping hard, the cursor goes where I expect. No wobble, no drift, no surprises in the middle of a fight.

No creaking, no flex, no plastic seams catching my palm. After years of mice that looked aggressive and felt hollow, this is a relief.

Same routine, same sensitivity, higher scores within a week. The sensor and the weight are doing the work my old mouse was fighting against.

Light enough to flick, heavy enough not to overshoot on small adjustments. That combination is rarer than the spec sheets suggest.
