Popcorn Maker 5 "Brilliant piece of kit" Mr Richardson 11 November 2013 I've used this for over a year now and it works perfectly every time. Remember to fill the mini container to between the two marks and use corn that is not old and is kept airtight (as it's the moisture in the kernel that causes it to pop). I tend to put the microwave on full for three minutes and stop it after about two, when the popping gets to about a second between pops. In my experience around 90% of the kernels pop - and you are left with a healthy quick snack. I've tried the air poppers and another microwave one, but this is by far the best.
