I have no regrets with this keyboard. I was definitely not looking for this keyboard originally. I was going to settle for a keyboard that looked like a typewriter. I didn’t know I was settling though. I didn’t know I wanted one with crazy lights on it. I am shook to my core. Everyone has asked where I got the keyboard from.

Ex Output:
positive


Ex Input:
