How is the fava bean cultivar 'Stereo'?

cv. 'Stereo' reportedly has stringless edible pods as well as edible beans - Has anyone grown it? If so, how did they turn out?
Also, has anyone transplanted fava beans successfully? Here in North-Eastern North America (NENA), our hot summers end fava bean production - I wonder if early fava starts, transplanted as soon as soil can be worked, might extend the fava production season usefully.

Received 'Stereo' seed, will grow and report further. I plan to start in the greenhouse, then transplant out as soon as soil can be worked. This all depends on getting water from spring to greenhouse...

Transplanted Stereo fava bean plant in Colrain MA.

Favas transplant easily. That big seed stores a lot of energy to get them off to a quick start.

I also love sprouting favas indoors, and planting them out soon after the radical emerges.

I recommend planting them much earlier than that. As soon as the snow melts, or as soon as the earliest of spring flowers emerge if you don't have consistent snowcover.

I typically plant favas into beds prepared the previous fall.

First 'Stereo' flowers:
