“I bought this a while back because I just needed ANY keyboard as my main board broke and I didn't have the time/money to replace/fix it. When I saw the price of this I was very skeptical but figured it had to at least be better than your typical e-waste…”
“It is alright just the keys are not the best and got no rgb led lights”

“Keycaps are dyesub, but still PBT Tactile switches feature a proper tactile feeling with great typing experience The case feels and looks really premium layer activation could be nicer but in the end you just gotta get used to the board”
