I've spent the past month testing Keychron's concrete keeb and it's absolutely brilliant, with one small sticking point

This month I've been: Testing an extremely heavy keyboard while benchmarking many, many graphics cards. Also, a spot of overclocking. Nothing caught fire. Victory!

When I first learned of the Keychron K2 HE Concrete Edition, I was both intrigued and confused. On the one hand, I was aware of the existence of the standard keeb and that we'd given it a massive 88% in our review. The addition of a concrete shell for extra heft? Sounds interesting.
