This is an awesome alarm, and I highly recommend it! There is such a delay from when my boy wets and when the alarm goes off that he has to wear a pull-up over the underwear
This system works perfectly for him, because as soon as he starts to go the sensor recognizes the wetness and the alarm goes off
We had to take the battery out of the alarm
The water slowly saturated the brief and the alarm sounded
I reset the alarm and made sure the volume was all the way up and set off to bed
As with all child related situations, approaching with patience and consistent obedience will yield the best results
