Keychron K4 Pro
7 owner reviews
“I previously had a normal K4 and i love the new one, the only thing is that the stabilizers lube work is kinda bad and the space bar was very rattly but after some lube work the K4 pro retakes the perfect productivity keyboard.”
Keychron Q9
6 owner reviews
“Love the keyboard and goes well with the switches i got. Size was bigger than expected but weight is truly high quality Could do with a force break mod though as it is a little pingy”
