Hey
They are on sale at Kiddie Care at the moment, £19.99 for 200 - so we did our research, as we were a bit sceptical, and they get really good reviews online! Plus, if you do not use all the nappies you can return them for a partial refund/next size up (as long as the white bag hasn't been opened - 50 nappies to a white bag).
I'm only 29 weeks, so have not actually used them- but they do get excellent reviews.
Hope this helps.
