“I am really enjoying using AULA f99! UX is 10/10 The only negative thing is the battery indicator, I find it quite confusing therefore I turned it off alltogether.”
“Good product - poor service. The order wasnt filed and the stock ran out. Then for the replacement item to be filled it took way too long for the order to arrive and complete a customer build.”

“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…”
