.. i dont think a mouse is something that is well suited to BIFL. Like, a toothbrush. Keep in mind you will need to replace the feet fairly regularly, at least every couple years, more if you actually use it *for sport*.

I've been playing hours daily of FPS for, idk, 15 years now, have never ever EVER in my life even seen a frayed mouse cord. Including every mouse anyone else owned, or at work, or casually in any PC situation. I have to think that there's something about your setup that is making it fray more than normal. My current mouse is, idk, 4 years old? 5? and has zero fraying.
