“This is my favorite keyboard. After assembling my desktop pc, I had always felt a little awkward typing on normal sized mechanical keyboards. This keyboard solved that for me. I currently use mine for my desktop, and on the go with my Steam Deck.”

“This keyboard is exactly what I was looking for. Low profile, great switches, not uber gamery. Very happy so far, hopefully it keeps working for a long time.”
