This product is genius. No wires just a simple pair of very ordinary looking pants, I cant stress this enough, because if they had been unusual my son would not have worn them. There are two press studs at the waist band where you attach a small one inch square receiver. You plug the alarm into the nearest socket and that it. The alarm goes off as soon as a drop of urine is detected, volume is adjustable, your child resets it by pressing a button, goes to the loo and changes into the spare pair. Obvisouly the alarm will keep sounding unless you change pants.
I only wish I had heard about this sooner, I put off the local bed wetting clinic twice, invested in waterproof matresses, covers etc and even tried those awful pyjama pants but this is the only thing that has worked.
Day 1 - novelty - alarm didnt go off at all and had the first dry night
Day 2 - set back - forgot to switch power on
Day 3 - alarm went off, went to loo, dry bed, changed pants
Day 4 - ditto
Day 5 - ditto
Day 6 - ditto
Please dont let the cost put you off, after experiencing dry nights now I think I severly under estimated the stress bed wetting caused for me and my son. The daily extra washing, the smell I just wished I had known about this sooner. I cant believe this is the only review.
