Ariived today, 14 days after ordering. Easy to apply and grip feel and texture is excellent. I use a fingertip grip, and now my G305 is so much improved! Very happy.
It fits my G203 pretty well (it's similar/identical as G102). Pretty nice to hide wear signs of my 3 years old mouse. It's also pleasant to touch and grips well. Im not sure how long it will last, but looking at the price it's well worth it.
