Bought the angelcare nappy bin after reading reviews online and my husband was sceptical about buying essentially a glorified bucket just for nappies. However, it is a fantastic product and we now both view it as an essential item for our newborn son. Nappies are disposed of quickly, without mess or smells. The system is very easy and quick to change. The cartridges last a long time - just make sure you squish the nappies up in the roll before you cut off the plastic to maximise usage - we are now on the 4th refill since he was born and our son is 2 months old. Perfect product and would recommend it to any new parent.
