Praise
“Totally enjoying this keyboard. Weight gives a quality feel. Love north facing RGB and effects. Price is in a sweet spot. Happy that I didn’t allow lack of reviews to affect my decision. Highly recommended.”

Critique
“Originally had purchased (2) J5 keyboards for staff in the office in January. Upon delivery, the top number row of one of the keyboards did not work and had to be RMA'd, within a few weeks the second keyboard refused to work altogether. Received a replacement…”

Praise
“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.”
