Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Q: I'm sure the information presented in this class is good, but the presentation set my teeth on edge. Sheri thinks she is funny when she talks in a screeching voice and makes fun of new mother's foibles in her "funny stories". I cringed every time I heard her squeal as a pretended mother with a problem. If you can get past her, then I guess the DVD can give you the information and techniques you need for Lamaze. But unfortuanately Sheri spends more time talking or shrieking while trying to be amusing than just giving the information you would like to hear.

A: Negative

Q: I have a small business and it was important that the envelope feeder work well. From day 1, this has been a nightmare. Components of the printer block the envelopes/labels and they don't feed properly. If you use internet postage, you lose money with the misfed labels/envelopes. I'm very disappointed and am shopping for a new printer now, only a short time after purchasing this one.

A: Negative

Q: My son is a HUGE bat man fan. This was a must last christmas.. well we never could get it to stand up right and then bat man wouldnt slide down with out him pushing him the rest of the way. It came apart no matter how easy he was with it. And he lost interest less than a week of tring to make it work. He still wants a bat cave so we bought the older version (that has great reviews)instead this christmas so hopefully this one will be the one to make him happy and my pocket book.

Negative
