LTC Nimbleback NB831 Wireless 75% 3-Mode BT5.0/2.4Ghz/USB-C Wired Hot Swappable Mechanical Keyboard, 81-Keys RGB Compact Gaming Keyboard with Knob, Sound Absorbing Pads, PBT Keycaps, Pro Driver

None. I’d go with this one: https://a.co/d/057JrAWM I bought the brand as a safe, low-cost entry to the mechanical keyboard world. It was perfect in every way for 1/2 the price. All the money I had put aside for a big, expensive custom keyboard instead went into custom keycaps. (Check my history for my two customs) Edit: I just checked my Amazon history because I couldn’t remember the exact number but, I have now purchased 14 of these keyboards and given away 12 of them to friends/family that liked mine. Every single one of those people love this keyboard.
