I've spent around $300 on 2 of these. Out of a years worth of wetting through, with a night nappy, I've only had to not wash his quilt twice ever, so these have worked probably less than 1% of the time. So he sleeps under what is essentially a ventilated garbage bag and the urine still gets through to the quilt. On top of that, his PJ pants or conni undies end up stuck inside these on the line, so they get musty until you have to turn it inside out to dry the other side. Our main aim is to not let there be shame, by there being as little fuss as possible. So these have less is feeling defeated and exhausted. And my poor little guy embarrassed.
