they're bloody fantastic! better than the pampers - both stay dry and active. not as small fitting but last night DH put one on DS- who's a heavy wetter at ngiht and he woke up 14 hours later bone dry, no explosions or anything. with pampers he'd have been soaked and been damp around his tummy area.
a def plus for me. (better than the tescos ones as well as they're a smaller fit than those ones )
wish i'd tried them 18 months ago! lol.
