The microwave popper that really works! Pops with or without oil for popcorn the way you like it. Leaves virtually no unpopped kernels. PowerBase and PowerCup concentrators combine to focus microwave energy so effectively that virtually every kernel pops. Yellow, white or hybrid popcorn pop fast—up to 3 quarts in as little as 2 1/2 minutes. PowerCup concentrator can be used for multiple batches; a supply is included. Salt or other seasonings can be added before popping for easy, even distribution. Works in most any microwave over 6 1/2 inches tall by 10 inches wide. Bowl and lid are dishwasher safe. Base wipes clean.
