“I’ve never used a keychron keyboard before and am disappointed i hadnt learned about it sooner! The keys are solid and the keyboard works better than expected.”
“Just purchased this keyboard but immediately found out that the backspace key does not work (literally just unpacked it from the box) - tried testing it on Keychron’s key tester and doesnt register at all… Did not expect such poor quality given the price”
