I haven't had any leakage problems with them. But, I have had 3 nappies velcro tab rip completely away from the back of the nappy when trying to put it on.

Also we are finding that the elastic leakage guard is really making a red mark on her bum, so much so that she complains about it. Well, she tells me ouch when I wipe over it.

I have kept aside the 3 nappies and the tabs as I plan on making a complaint about them.
