Hand Size Guide

These are not exact measurements, only use them as a rough guide:

  • Palm Under 19cm / 7.5″
  • Claw Under 21cm / 8.3″
  • Fingertip 17-21cm / 6.7-8.3″

General Thoughts:

This is a niche mouse… meaning it’s not for everyone and just for the few that like having their ring finger rested. That’s a personal preference. So if that’s what you like then this is a great option. It’s 102g but inside there’s a weight (see the review). It can be removed and that will bring it down to about 88g, which is quite light. If you need replacement mouse feet and you didn’t get them in the box, then contact Cooler Master.

It’s great to see Cooler Master stepping up their quality here. After the disappointing MasterMouse S, it’s very promising seeing the build quality of their latest mice, because we might see their better shapes revisited soon. I’m a big fan of the design of the MasterMouse S and L… those feel amazing. The latest MMs are good, but their shapes will always hold them back in my opinion… they lack the wow factor. Either way, solid performance with the 3360 sensor, no real issues, definitely worth checking out.
