The mouse felt incredibly sturdy despite its weight, and the 8-kHz polling combined with a 44k-dpi sensor makes it the best-performing mouse on this list.

I found it difficult to comfortably grip this mouse for prolonged use, and friends with smaller hands found the same. Regardless of hand size, a larger vertical mouse is typically more comfortable for most people. It's worth noting that the Lift is one of the only vertical mice I've tested with a left-handed configuration.
