4.4

The 8000Hz polling option is a headline feature, even if some reviewers found limited real-world benefit.

portability
Product 1: GravaStar Mercury V75 Pro
2.6

Portability is a weakness because the board is heavy, wired-only, and visually or physically bulky despite its 75% layout.

4.7

The OPX switches are usually described as smooth, quick, and satisfying, with a few comments about sensitivity.

switch options
Product 1: GravaStar Mercury V75 Pro
