Query: 80% UNPOPPED KERNELS

This popper is awful! After putting in about a half cup of kernels, AT LEAST 80% of them flew out of the machine before if was even hot enough to pop the rest of the kernels. The fan at the bottom blows all of the kernels out of the chute. Save your money and buy a popper that has a spinning bottom WITHOUT a fan that blows the kernels up and out of the chute. Total waste of money!
