“It’s nice but if it was with the volume thing on the top right like in the aula 75 it would be much better”
“When I charge the keyboard it only holds for like 10 hours and then I need to charge again”

“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.”
