I have to be honest, I haven't read good reviews and I wouldn't buy them myself. There are so many other brands and/or systems of nappies on the market that perform better, feel nicer and look cuter. And more simpler (pockets or AIO's). BUT, in saying that they are still a very popular brand so they must work for some people. I just wouldn't advise buying in bulk (of any brand) before you can try.
Brands that I've tried & would recommend are Fuzzi Bunz, Honeychild, Foxybots, Itti Bitti D'lish and Designer Bums. There are HEAPS more that I'm yet to try though
