I have a couple, I like them, but they are not the best fit on my son (who suits narrow crotched side snapping nappies, BPs are wide crotched). They do have a good rise which I like. They do work on skinny bubs but can be a bit 'bunchy'.

I do wonder whether they might be a better fit for girls - when snapped at the front, the insert bunches at the back and doesn't cover his bum properly, but snapped at the back it can have the opposite problem and doesn't have the coverage at the front. I've heard that some people with snap presses put snaps on the other end of the insert which apparently helps. I also find that the elastic digs in at the legs - maybe because the casing roll is narrow it is not as soft as a wider casing or an uncased leg. But that also means the containment is really good, I used BPs from 6 weeks and never had a poosplosion, unlike an itti.
