Let us get right to it - Dave gave the KM-G3 a Great Value award, and it costs $64.99 at this time. For $5 more, you get software support that opens up many more customization options as well as Outemu Brown switches for those who do not want clicky switches. If that does not merit the same award or better, I do not know what will.
But wait, what about the Motospeed Inflictor CK104? You see, that is the keyboard that has been mostly re-branded as the Aukey KM-G3 and KM-G4, and it comes in at $15-25 less depending on whether you are open to purchasing from an Amazon fulfilled third-party seller, or random sellers on Aliexpress/Taobao. The KM-G3 in particular is almost an exact rebrand too. The KM-G4, on the other hand, is not - be it because of the Outemu Brown switches as opposed to nothing but the Blue switches as an option on the OEM options, the 24-month warranty instead of the unknown-1 year warranty, or the software driver support I am not seeing a mention for with the OEM versions.
At this price point, the KM-G4 offers tremendous bang for your buck even if the OEM version was not a factor. There is not much to fault here apart from the cons mentioned above, and the only thing to really worry about is that the secondary legends might wear out to the point where you can not read them anymore. The manual is thus worth holding on to. The software driver also is not perfect by any means, and if I would have had v4.2.0.5 for the duration of this review, things would have gone differently, but Aukey quickly worked on the bug based on my feedback and put out a stable public to where I am not going to score against that - within days. This is a really good keyboard, and one you should strongly consider if looking for one in the the sub-$75 market.
