we had a long discussion about them here when they first came out, I had bought one just to see what they were like, so I measured every bit and reported back, and although there is not a full beespace above the frames (either with the old roof, or the feeder) there is nearly a half beespace.
I've never noticed any crushed bees either.
A little later that year (Spring convention I think) I spoke to Eric and Jon at Maisies and the Maisies nuc was just a copy (made by the same manufacturer) of the same nuc they had been using and overwintering bees in at Maisemore's for a few seasons. They never had an issue with the 'no beespace roof' either.
