Presto32 Genuine Powercup Microwave Popcorn Popper Concentrator-09964

My frigidaire microwave burns up my concentrator before corn is popped! Only good for one use! What setting can I use?

Can you only use these with the Presto popper, or will they work with other types of microwave poppers (assuming they fit)?

are there diff size cups?

Can these also be used in a silicone microwave popcorn popper?
