Mmmmm.
Like the top beespace + 'rails' (not too sure about the ruggedness of those rails though.)
Like the top feeder, but like Park's poly nuc its a Miller type. Now, that maximises the number of bees that can feed, thus the speed of take-down, BUT being shallow it needs the hive to be very accurately level - personally, I think an Ashforth (access at one end rather than the middle) is a better design for a *shallow* feeder - you put the bee-access at the lower end. If a shallow Miller isn't level, filling only the 'upper' half tank is the way to go.
Like that the feeder detailing provides for a cover over the bee-access (none of the silly idea of using the roof for that).
Like the 14x12 eke option.
Entrance looks OK - like the idea of the alighting board (but the implementation isn't exactly pretty) however still for a swarm-gathering box, it will (just like Paynes current offering) benefit from some foam all across under the front to prevent bees 'undershooting' and gathering on the underside of the floor.
Apart from the fact that the roof still looks a bit thin, you might think it had been created by someone that had read the criticisms of Paynes' one and done something about it. I wouldn't believe anyone that said the designer had never even caught sight of the Paynes one! But then, this could be the Paynes 2.0 being licensed out, like they did with the earlier version ... and breaking cover away from 'home'.
The price quoted on Maisemore's website (identical to Paynes basic National nuc) might even support that hypothesis.
Be interesting to see what happens. I'm not actually needing any more nucs right now, but I could be tempted to try this one.
