My granite set arrived today. However, I'm not very happy with it. Virtually every key bigger than 1.25u is warped to the point of being unusable without working it over with a hair-dryer. Essentially all the stabilized keys are warped enough to cause Cherry plate stabs to hang. Many of the keys have visible cruciform mold irregularities on the key face. Almost all the keys have some level of light scratch marks from rubbing against other keys (during shipping?).
Not the best photo of the scratches but you can kind of see it
6.25u spacebar warped badly enough it causes Cherry plate stabs to hang
Caps lock keys are a good average for the level of warpage, some keys are worse than this and some keys are better
I don't think I'll be ordering anything manufactured by SP ever again and I'm about 2 seconds away from cancelling my Deep Space order. For the amount of money these keys cost I'm pretty disappointed. I didn't have anything like this from the $20 BangGood PBT set I bought and the Granite set cost 5x that much.
Also, I thought these keys would be packed in that nice little black and blue box from SP with the DSA "thank you" keys on top, but the bags of keys were just thrown into a brown shipping box.
