I went to one of Black & White's cafes recently on a trip to NC, it was one of the best drinks I've had at an east coast cafe so far.
Totally fair, I don't know how the current ones stack up. I think I have the first version and I personally find it very fiddly, a huge mess even with RDT, retained nearly 2-3g with a clean burr chamber, had very poor consistency, and even worse grind issues before I got an anti-popcorning device. Fines everywhere, especially if you use the bellows (because the bellows push down on the upper burr carrier...).
My shot consistency was horrible using the same grind setting, dose & tamp, with shot times varying up to 10 seconds. My shot times with the Sette 270 are consistent, within a couple seconds. One of these days I'll muster up the effort to check/align the burrs and mod the clump crusher and give it another shot. Also interesting to see it's actually dropped in price since I bought it.
