This set is so much better than my doubleshot WoB ePBT I bought earlier this year. The keys actually sit like a half mm higher than the abs ones do, which means there is no interference. the ABS keys have slight interference on row 3 with standard south facing switches, which I didn't even notice until I got this set. I don't yet have any GMK sets, but this ePBT set is super nice and if this is the quality I can expect going forward I will continue buying their PBT stuff. Also spacebars are straight.
