I just received my Whitefox keyboard today. Vanilla layout, prebuilt with LED lights. Gateron Browns. I am quite happy with the overall quality of the keyboard. There is no sticking or binding of the keys. All the stabilizers seem to work just fine. The provided allan wrench is not that great for putting the screws on the face plate on and off as it does not provide a tight fit and you run the risk of stripping the screw or uneven fit of the screws into the base plate. I used a T6 Torx screw driver and that worked much better. Overall, I am quite pleased with this keyboard. The clean font/color and feel of the PBT keycaps are fantastic. Kudos to Massdrop.
Wayne_Campbell_Fan+1 on the bad allen wrench. I gotta go get my set out of the garage to work on this thing. I'm actually thinking the screws might be a bit off as the included wrench fits 2 out of 8 of them perfectly. Otherwise I'm satisfied.
To everyone bi***ing about flashing the keyboard - I'm a novice with mech keyboards and it took me about 30 min to flash to the True Fox layout from the default included one which had my backspace key mapped somewhere else in the upper right.
I haven't noticed much QC issues with mine other than the screws/allen wrench. Beautiful keyboard!
