[EX Q]: I bought these. After two uses (the first being a french vanilla cake, and the second fudge brownies), they stained from the brownie batter and will not come clean. I figured these would be better quality, since they ARE kitchen aid.
[EX A]: Negative

[EX Q]: On a number of occasions, it had been suggested that I read this book, and I must say I'm very glad I did. I got very involved, as the writing was so wonderfully descriptive. Having said this, I don't think it was arduous to read all that detail, which sometimes makes reading a book feel a bit of a chore. I would recommend it to anyone!
[EX A]: Positive

[EX Q]: When I run the software installation, it loads it's two executable files into my startup directory. This shouldn't happen.When I try to launch the emarker software, it says "Cannot initialize encryption, Application shutting down".I e-mailed their tech support for some ideas and the responder said they didn't think the software would work with Win98SE. ?????
[EX A]:
Negative
