Great product - give it time, it works!
We purchased this alarm because our 5 year old is such a heavy sleeper, and he was frequently wet through the night.  During the first few nights, the alarm would wake me up and I would run to find that it was too late, he was already wet.  But I would bring him to the bathroom anyway and did that consistently for a few nights.  After that, the alarm started waking him up and he started going to the bathroom on his own.  After about a week, he was completely dry through the night!  He has even stopped wearing the alarm and is still dry through the night.  This product has worked wonders for us and I have already recommended it to a coworker whose son is having the same trouble.
