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

For Presto popcorn maker. Uses regular unflavored popcorn straight from the can instead of the more expensive microwaveable popcorn. Add your own oil and/or salt if you like before you pop. According to the instructions, the concentrator is reusable ("up to 12 times if you use oil; 24 times without oil”). I haven't tried to reuse them. We use some oil. Makes great popcorn - and very quickly in a 1200W microwave. Very few cores which I cracked after about 4 minutes on high power.
