I bought this for my husband at Christmas. His first thought was that it was just a bit gimmicky, but he has recently been using it more frequently and thinks it is great. His only complaint is that he often puts 2 hotdogs in each roll, and there is only space for 2 hotdogs and 2 rolls at a time. If he wasn't so greedy, this would not be an issue!
The only problem I have come across is that a lot of the supermarket fresh rolls are too big for it. The best ones are the prepacked packs of 8 that most supermarkets stock.
One other complaint. As I said, I bought this for my husband, but I'm the one left to clean it:))
