Negative Positive
Title: This is Junk.
Review: I read the entire book, spent a good deal of time working with it. The functions don't work at all. Only the digital scale works and it is questionable. I can notice a 2-4 pound range on the same floor surface over a 5 minute period. This is junk. I give up and I'll never buy another one of these again, it was a complete waste of time.
