Forced air or "fluid bed" roasting is a real thing, it is exactly like a popcorn popper. I don't see what your talking about, they say the whole thing is 1.3KW, this includes the motor and heater.
However...I'd be wary of wood in a cooking appliance. Not sure of the quality either, it could be a scam in that it's just a crappy hair blower style thing inside. They say they'll actually sell spare parts. Are they being nice...or just engineering to fail?
"It's expensive because it has a one year warrenty" Yeah...that's what they all say...then it breaks after exactly a year.
"Beautifully handcrafted"
Then why is there a huge separation between the base and top plate, plus a bunch of scuffs?
