I've just received my set in Romania on 03.05.2018. Ship date is 16.04.2018. It looks and fells better than I expected. i'm quite impressed.
Still, I have a problem. The space bar is not comming back to the same full height. There is still half a milimeter difference and it's driving me crazy. I can use my finger to pull it back up. With the old space bar keycap everything works just fine. I'm using that atm untill I find a solution. There is no noticeable weight difference between the two space bar keycaps.
