I have about a dozen of them that I bought on EBay before I found out about the real MCN lol They are REALLY bad.
Having said that though, with a NB who you are changing very often anyway, and trying to guage how much they are weeing and when etc, so it is important to be able to know how much they are weeing they are actually quite good - because you have to change them everytime they wee!! lol
I still use them as backups now, but I wouldnt buy them again or have them as my first and foremost nappies.

Check out buy for baby too, you can find some second hand nappies on there cheaper and you can trial and error. But until you know what you want and what NOT to buy, steer clear of EBay!! lol
