We used this popper last night for the first time. It worked well, though threw several popped kernels on the floor in its enthusiasm! There were quite a few unpopped kernels (old maids, we call them), and the end result was rather chewy, instead of crisp. I don't know how much of this, as well as the old maids, was due to the brand of corn we used (Orville Redenbacher's Gourmet Popping Corn) plus the extremely high humidity around here the past few days. Have used O R microwave corn and it is very crispy. Will withhold final judgement till we have used it a few more times.
