Query: Very Unreliable Product

This product seemed like the ideal solution for my six year old's problems. It would be, if it were at all reliable. Unfortunately, it only works maybe 30 percent of the time. Most nights, my son wakes in the morning in a puddle having worn the stupid things all night with the alarm not going off at all. My husband messed with them trying to get them to work and says the wiring sewn in the undies is really crummy. You have to fiddle with the wiring to get them to work. How do you do that every night?
