Just received my board a day early!
Compared to the Kentucky Wildcats I had a couple years back the quality is about the same; the casing feels a bit stiffer likely due to having less case but the front seam looks like if I dropped the keyboard it would come apart in the front.
All the clacky goodness is there although going off memory either my hands have gotten stronger or the spring action has gotten lighter - or both. Doesn't feel as stiff as my previous Unicomp but again this is only after 5 min of using it.
All in all 8/10, would buy again. If MassDrop does another beige on black Unicomp w/ an option for 103 setup (which looks infinitely better than the new 104) I'll probably pick it up.
