“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.”

“I love the keyboard! Everything was as expected but the keys are even smoother than I could have hoped for. I love the color, it matches exactly what was displayed on the website. Setup was very easy once I actually read the manual. I like that it gives you…”
