I have used an air popper, a glass microwave popper, and a stovetop popper. Somehow none of them satisfied me. Looking for yet another alternative, I came across silicone microwave poppers. After reading reviews, I decided to try the well-regarded POPCO popcorn popper. What a great choice! I have used it a half dozen times now and am very pleased with the resulting large, light, and tender popcorn. My microwave oven is a 700 watt model. It takes the popcorn kernels about 3 minutes on high to complete a popping cycle. Unlike some reviewers, I do have some unpopped kernels at the end of the popping time. However, it’s not enough to be a concern, perhaps about 20 out of 1/3 cup kernels. The POPCO popper is easy to clean, at least for me, as I use no butter or oil until after turning out the popped corn into a serving bowl. I just give it a quick rinse and let it dry. Storage is no problem; it folds down to about 2 inches in height. Since it’s made of a soft silicone, it won’t scratch, chip or otherwise damage anything it is set on or in. I cannot yet speak to durability or longevity, but it seems that if used properly, it should last for years. The POPCO Popper is a bargain for its price. I would definitely buy again, and recommend it to other popcorn-loving folks.
