I tried all the ways, this is the easiest and with the least oil.
I am still experimenting with temperatures and duration in the oven, because my popcorn often burns, but I will find it.

Much easier than an air device where you sit and make the goalkeeper.
45g is a good quantity for each one, with 50 coming out.

Another advantage is that if you want, you can mix with minimal oil/butter (1-2g) and fine salt or another spice, and in 3 minutes they have all popped, they are crispy and have a light flavor.

In our 800W one, with 50g it took 2.5 minutes, at 3 they popped and the last ones.

Very convenient, you have ready popcorn in 2-3 minutes, without even using oil. I eat them straight from there. You don't dirty a bowl and it washes very easily. In the oven that I tried it to see if it works, the corn never popped.

A little expensive, but it works very well. It takes up no space at all and has the same result as an air popcorn machine.

To work properly, it needs both of them together. Otherwise, it requires less wattage in the oven to avoid burning them.

One "ear" of the utensil broke very quickly (it got cut), a few times the "ears" opened causing a quantity of the corn you throw to burn.

I am very satisfied, quick popcorn and without much mess.... but above all, it feels like being at the cinema...

Finally, I managed to make oil-free popcorn in very little time and very fluffy. Get it. It's worth its money.

It is an amazing product, I highly recommend it! Much better than an air popcorn machine. You don't need to add oil to make the popcorn, and the quality of the "pop" is much better than the machine. They won't turn out rubbery, they will be very crispy as if you made them in a pot with oil. (They have half the calories, for those who are interested)

You unfold the device, add popcorn up to the mark, fold the top to close it, and put it in the microwave. After 2-3 minutes on full power, the top will open by itself and fill up with popcorn. I never expected to say this, but I like them more than the popcorn made in a pot with oil. However, if anyone wants, they can add oil, but in my opinion, I prefer without.
