How dirty are some of your hands that the main concern is the holes in the mouse...
Not dirty but realistic about human skin and how it works for everyone.
This isn't even about sweat, its about all the bits you lose and all the dust flying around everywhere. No matter what you do, you will be opening this mouse to dust it out and you will want to wash the shell from time to time. Every time you do this is creating more wear and reducing mouse longevity.
I don't know about you, but that to me is a clear case of too much effort versus the benefit of '68g'.
Regardless, seems like a very solid mouse otherwise. I'll take a closed shell one any day with a slightly higher weight on it though.
There is quite a noticeable difference flicking around a 60gm mouse VS a 120gm mouse in a fast paced FPS. I highly doubt anyone really "tires" from a heavier mouse, but when something is half the weight its hard not to notice.
Absolutely true. I went from a Zowie FK1 to a (currently) Logi G502 and that's very comparable in weight difference.
Yes, higher weight is different. But it usually is also found on different mice. This G502 is more of a palm gripper really, and for those ,weight is beneficial up to a point. That said I would not have been bothered with -20g on this mouse, 120g is on the heavy side. But it never impaired gameplay for me. Its really just what you're used to, and you can get used to weight as well.
For claw grippers low weight is beneficial because of the more sweeping movements you tend to make with them. But even then, there is absolutely no need to fuss about a 80g or 90g mouse. I would have bought this Model O if it
didn't have the holes to get to 68g... Its just a very, very stupid kind of tradeoff and not one that is aimed at longevity. That alone is a dealbreaker, I don't buy mice to replace them every year.
