Received my Ducky Zero today. Only used it for 20 minutes but loving it already. The force required for the Backspace, Enter and Shift keys is taking some getting used to but other than that it's so easy to type. It's also kinda weird having a normal straight space bar and the "standard" configuration for the navigation keys (Home/Delete/End/Page Up/Page Down/Insert), since I haven't had those for at least 10 years.
I don't usually rest my wrists on the desk when typing but I still bought a wrist rest for gaming. Also, the Cherry MX Browns are no louder than my previous membrane keyboard. In fact, I think they may be a tad quieter. :O
