They try to prove people either 'palm' their mouse or 'claw' it (and sometimes 'finger' it, which is a subset of 'clawing').
This, doesn't take into account the obvious: What if you finger/claw it when you want to move it in an awkward way and then you palm it when you're cool and no much movement is needed?
They try to sell mice that are 'specialized' for grip and that may explain their obsession with categorizing players, but I don't think it's really important.
Also, I believe if someone ONLY claw grips,it may be a sign of a very stressful individual. e.g. Why would claw or finger grip when flying to an auctioneer. This is silliness. I would palm it to be cool and comfy.
gtfo razer, go to logi to teach you how to make mice.
though you're good at pads, the pads are good.
