Please share feedback. I wrote the review so others would know. I've never written a review before. Bought this for The Boy, age 8. Wild sleeper, so we needed the expensive underpants, wireless system. He was soaking a pullup every night, sometimes leaking through to the bedding, so I expected it would take a long time. Results: week 1, one dry night. Week 2, 3 dry nights. Week 3, 6 dry nights. He dealt with the alarm, changing pants, resetting alarm all by himself. Imagine his pride, when he announces each morning, ”I was dry again, Mum!” It will also have saved us a fortune in pullups. I am amazed!
