“So far it have met my expectations for the use i wanted it for, had a small hic up the first day i started ysing it but got easily resolved with the provided user manual”
“The keyboard is smooth to the touch, and has the nice feel. For me, it's almost an ideal keyboard but the one thing that gets me and it's a hard issue is that when connected, it takes away input from my controller when I game, especially for live service…”

“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.”
