Title: causes microwave oven to spark
Review: I've been using this Progressive Microwave popcorn popper for many months and I agree with all the comments about it not popping all the kernels, burning kernels, etc; however, I have a new complaint that I thought would be important to pass along. After many uses, It now causes my Microwave oven to spark. I've tested all the other dishes I use in my microwave to isolate the source of the sparking and it only happens when I use this bowl. I've never had any sparking occur in my microwave before this. The popper is going in the trash.
Is the review positive or negative?
