I have received this product as a Christmas present and held it so far, especially for a nice gag. After the first tests I have to say though, that I am absolutely amazed. You can work well with this product and you can actually manufacture chips in the microwave. No strange potato slices, but just real chips. Am now at least as fascinated by my microwave. Of course, the disc has only limited space, but given the relatively short period which is not really a problem. Oh yes, I've used more 7 than 3 minutes. And: Even with me the disk was bigger than the microwave dish. However, it went that way.
