Well, Aukey has done it again. The new KM-G6 effectively replaces the older KM-G8 at the same price point to where the KM-G8 is now an end-of-life product. We arguably get a better built keyboard with the plastic bottom panel overlapping on the front to provide more structural integrity, a different logo placement, and, more importantly, backlighting with more onboard controls. The PCB is also re-worked to accommodate these additional features, so it was more than just a small tweak here and there. Most of the rest remains the same, which may or may not be to your liking.
Take the switches, for example. Outemu Blue switches are not going to be anyone's switch of choice from the get-go, but they do a decent job; however, I can't say anything about their long-term reliability. I do wish they would re-work the legend placement for the keycaps so that they can be larger and occupy more of the available area, especially for the keyboard-specific secondary legends that are cramped on to the keycaps. While Aukey is at it, have the secondary legends be doubleshot injected as well. If this means a small price hike, so be it. I would rather have a $50 keyboard that lasts for several years than a $40 keyboard that needs a $20 replacement keycap set in a couple of years.
Some of the comments from the KM-G8 review hold true here, which means that one should not have any hopes for Aukey to make any changes with the KM-G6. Knowing how they operate, in a year's time, we will see another new keyboard at the same price point with even more features, perhaps the controllable, full RGB backlighting that is currently in the KM-G4. But the KM-G6 offers plenty to those wanting a more than decent mechanical keyboard without having it break the bank.
