Review on 32 Presto Genuine Powercup Power Cup Microwave Popcorn Popper Concentrator - Model 9964 by Stacey Littlejohn

18-18-2021: This company is fun! You solved my problem. Original Review: Why is this happening? The centers of these inserts collapse and burn the popcorn where the insert burns out. I have had a Presto popper for many years now and it has never behaved like this. It's been on the shelf for a few years, but looks great. However, it doesn't work properly. At first I thought the earbuds had aged a lot, but the new earbuds work the same way. It happened for the first time. These are extremely simple devices, so I can't put them together incorrectly. Any ideas? I use them with oil like I always have.
