anyone used these? I just bought a double roll set after the ones i got with my mothereases ran out and they seem to be crap. Im sure the pee just slides right off em out the sides of the nappy rather than going through and creating a one way system. Might have to take a trip to thats my baby and buy some mio ones today if it carries on as ive gotten rid of my leakies now and would rather not carry on having probs cos of stupid liners
