Input:
I love the concept of this popcorn maker and have purchased it as a gift many of times.  This is the number #1 go to for recommending a popcorn maker that makes the best popcorn. I am disappointed however at the point that this product keeps on breaking on me.  I try to carefully wash the product as instructed and find that the product does not heat up properly. I have kept on ordering 3 of these popcorn makers.
