Good quality, seller fast response, and awesome
1. The bottom 4 rows don't feel that good on linear switches (e.g. gateron yellow switches), but fine on clicky/tactiles (tried cherry mx, gateron blue, and Boba U4 switches). 2. The bottom 4 rows sound meh on linears but don't really make that much of a difference for clicky switches (blue), and I didn't really notice any difference on tactile switches. Space bar is good The bottom 4 rows are 2-3mm shorter than the other cherry profile keycaps that I have so that is probably why it sounds and feels kind of spongey. That said, I'm conflicted because I like the shorter keycaps but I probably won't be using them with linear switches. The stems are extremely tight. They keep pulling off keys from my hotswappable board, and is tight enough to move a 2.5kg (5 pound) metal keyboard. They're starting to become looser after removing them and putting them back on between keyboards, however.
