Oh, it's Greetechs? I see.
Greetech switches are also used in A4tech and Royal Kludge products. For comparison on price, RK boards with Greetechs are 299 yuan ($47.85) for the regular version, and 419 yuan ($67.05) for the RGB backlit version (also compare that to the prices Corsair charges for their RGB boards!). Interestingly, they (RK) also say that Greetech was at some point OEM for Honeywell. Reviews say pretty much the same things as they do with Kailh-- feels more or less like Cherry MX, with maybe some slight differences or inconsistencies. As with Kailhs, it's hard to know how much of the difference is reality and how much of it is people noticing inconsistencies that they wouldn't notice on Cherry switches because of the difference in expectations.
