First, let’s temper your expectations just a little bit. These are, obviously, not as high quality as some more expensive keyboards—but we were surprised at how good they were. Some of it has to do with general build quality, but a big factor is the switches inside.
The individual key switches are what make mechanical keyboards unique: their complex spring-and-slider construction gives the keys a much longer, more satisfying “feel” than rubber dome keyboards, which is why they’re so coveted by typists and gamers. German corporation Cherry has been manufacturing its patented MX switches for over 30 years, and while they’re not the only switches that can be found in mechanical keyboards, they are the de facto standard.
Since the patent on Cherry MX switches expired, competitors have made “clone” switches that are generally sold to keyboard manufacturers for much less. These switches have the same basic characteristics as Cherry MX switches, including cross-shaped stems that are compatible with the same keycaps, and different colors corresponding to different switch types. The main difference: these clone switches are mass manufactured in China with (presumably) less strict tolerances gives them a looser, more shaky feel than the genuine article. That said, they’re very much preferred by bargain-hunters, since real Cherry MX switches or equivalents cost about a dollar per switch, instantly putting keyboards outside the range of an impulse purchase.
In addition, these keyboards tend to lack more advanced features like programmable RGB backlighting (or backlighting at all, in some cases), detachable USB cables, and other niceties like that. You may find one of those features occasionally, but you’ll rarely find them all on one board.
Cherry MX switches come in different colors, each coded to quickly explain different variables of the switch itself: the strength of the spring, the “bump” or lack thereof at the point where a stroke is registered, and whether the key makes an audible “click” as it’s pressed. Other manufacturers have copied the color coordination scheme along with the Cherry MX switch design, so we’ve broken the recommendations below along those lines.
