The only real issue people have with WASD is the keycaps. The keyboard itself is actually really good quality
Keycaps used to be only engraved, then he added the option for etching. More recently, he switched to a UV printing process. I think a full hardcoat over a keycap legend is excellent and have some evidence that it's really long lasting. If you only want your keycaps to last for 5 years of hard use (7 days a week 18 hours a day) then they will be fine. If you use your computer less (like at work, 40 hours a week) then it should last longer. I figure that longevity like that is well worth the price.
Build quality is great. They are from costar (or were for the V1. I am reasonably sure they used costar as the OEM for V2, but have no real proof) and are of good quality. Should outlast your need for it, I think.
Enjoy!
