They look interesting but hard to find info on these things.
Can they cook anything that can be cooked in an oven?
Will spitting fat like on burgers e.g. hit the element (where is element placed)?
What is difference between 10 in 1 and 5 in 1?
How much power do they actually save?
They definitely look interesting. I already have a portable oven though that I now use instead of my normal full sized oven so will assume the power saving wont be maximum for me given I already have a shrunk heating space.
Apparently they are just small ovens really. So if I'm cooking a few hash browns and that's all I'm using the oven for I'd use this instead.
The fan is obviously much more effective as it's such a a small volume
