i bought some of theses nappies 2nd hand, and I think they are good nappies, however in saying that, i don't think they are worth the price tag (hence why i was lucky to get some practically brand new 2nd hand).

I use them as night nappies, as my lil boy is a heavy wetter. and use my other nappies as day nappies.
I also use pea pods at night time with boosters that I made, and they work just as well as the bummies.
