I bought this as a Valentine's day gift for my 9 year old son who loves star wars and peanut M&Ms too. Since I thought the yellow m&m character was the "peanut m&m" representative, I thought this would be great. It comes with a miniature package of plain m&ms which I guess should have been my clue that it wasn't made for peanut M&Ms, but I purchased a bag of the peanut variety anyway. Some peanut M&Ms will work, but many of them get stuck, break, and cause the dispenser to not work. Oh well, it's fine if you use plain M&Ms.
