Best praise vs top criticism for Cooler Master MM731
Best Praise
+7 pts“The "My mouse is too small" claw, that hybrids between fingertip. G703 and MM731 are my favorites in that realm (my grip is basically the same), haven't tried the vgn.”

+7 pts“Everything sounds alright, but gotta disagree with the m731. The shape on the right side of that is horrendous, ungrippable unless you grip ergos by stretching out your right fingers and pressing with your joints on the whole side. If you curl them, even a little, actually the worst ergo shape I've tried (tied with the rog keris)”
