Using those microwave popcorn cup things..

Has anyone else got one of these? I bought one today from an opshop, so it is missing the instructions. Its one of those with the white clip-on base that you put the corn in to, that is rather shaped like a donut, and you clip it to the clear cup section which acts as a lid while it is in the microwave. Know the one? I think Avon sold them at one stage?

I am hoping that they work well, as I really like popcorn, but can't stand the smell of hot oil/copha that spreads throughout the house. and using the huge heavy bessemer baking dish and lid trying to shake it around (plus add large belly to the situation, not good).

Anyway, how much corn do you put in, and how long for in the microwave? On high I guess?

Thank you!
