I am a new beekeeper, so what do I really know?
There are a number of experienced beekeepers that are trying it out - it will be interesting to see what they think of it after a season or two. The one danger is I think it will attract people that don't fully understand beekeeping, which would cause problems for other nearby beekeepers. I also don't understand how they determine moisture content in the honey. Third concern is if the design creates excessive swarming.
