We are just starting on a 1 week trial and besides the fact that Ivan hates it, I hate it too. Okay we're only up to the first calabration but it never alarmed, lost him, his butt is bleeding, and he's starting to react to the tape covering it. It's way bigger than I thought and... I guess I'm just not sold on it. Yes, yes, I'm 2 hours in to it so it's a little premiture but.... How long did it take you to love it, and then for your kid to love it?
