These switches were surprisingly decent out the box. Factory lube was okay I’ve definitely seen much worse. With that said I would recommend hand lubing these switches if you want to get the most out of them as I would ANY switch. They offer a nice clacky sound profile being on a polycarbonate plate, and even more on an aluminum plate. I’ve tried these in two keyboards. The epomaker ek68 and also the Mxrskey ck650. They sounded much better in the ck650 given that’s the keyboard with the PC plate. Quite smooth to type on with a decent rebound and solid bottom out. Give them a solid 3.8/5 solely based on the fact that there’s better out there for a cheaper price such as the Akko cream yellows. But still a solid linear switch!
