I did put a great review up for these nappies about a year ago, when I had been using them for a couple of months. Unfortunately my daugter is now 16 months old and the majority of the nappies are ready for the bin. The elastic just does not last, which is pretty poor when they are marketed to fit from birth through to toilet training. I also had to send 6 of them back after a year as the material was faulty - the waterproof plastic came away from the rest of the fabric. A real shame as they started off so well, and I spent $800 on them only to replace them. We now uses Baby Beehinds, which are a lot more generous in the sizing and are more absorbent.
The moral of my story - steer clear of Rumparooz if you're looking for longevity.
