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:
Once again Grace has managed to wrap me around another set of characters that keep me coming back for more and waiting with baited breathe! While this was NOT what I was expecting in the Virgin series, it stayed true to the Interstellar Brides series giving me characters that pulled me in and left me riveted from page to page. When I came to the end I am embarrassed to say that I shouts "NOOOOOOOO" for all to hear on the plane where I was reading.

Ex Output:
positive


Ex Input:
Great alternative to a round brush for getting your hair straight. Light weight and vented so the heat gets through better. I ordered after hairdresser used it on my hair.

positive
