Bought this for a Birthday in the family. Only pops around a haldful at a time, takes ages to warm up then switches off when it gets too hot, can't turn it on again until it's completely cooled down. Unpopped kernels stay in the middle tube and the only way of getting them out is to tip it over.
I got very frustrated over this product, we then bought a £9.99 popcorn machine from Argos which is brilliant! I'd recommend the Cookworks Popcorn Machine instead.
Oh and the Ethos Smart Planet blah blah is overpriced too, and is not a "game" unless the game is to get really irritated with it, in which case I won!
