Title: It was nice while it lasted
Review: I was happy with this product when it worked, but it didn't last long enough to justify the expense (in spite of the fact that I was very careful to follow all manufacturer's instructions). It stopped working on my first morning back to school, and as a teacher/mother, I don't have time for the last minute crisis it created. I'm looking for a better one to purchase, but because I didn't get my money's worth from this one, I'm worried about spending too much for the next one.
