WASD's excellent customer service has been mentioned time and time again, but it is really, really, truly excellent. It's a pleasure to deal with them. The keycaps are real nice as well, pretty much of a perfect thickness and they feel great, I actually find them to be nicer than Cherry corps thin PBT. The caps are about as thick as the PLU ones that were on the board before, but they are a LOT more rigid. The PLU caps can be squeezed/warped with ease, whereas the WASD caps require lots more force.
The engraving is subtle, and can be felt on the keys (the feel will probably decline with usage), but this is to be expected on lasered caps. It looks real nice and it's awesome to finally have a board that reflects what my key configuration actually does.
