It does look nice enough to use it as a conversation piece when you throw parties, so there's that, over juicero. I think that must appeal to a certain type of person.
Yea if I was cooking for someone I would feel better about harvesting food from this device than "hold on a second while I get this bucket out of my cupboard."
I agree. Mushroom growing needs to be hygienic but depends on conditions that are not normally considered hygienic. Having some help in terms of the inputs and conditions would provide reassurance. There are lots of products like that in the kitchen that take something relatively easy and make it more consistent.
