I love the super soaker pads, so i can use the same shells for both over night and daytime with different liners. the snap-in feature is great. the only drawback to these diapers is that there isn't a separate snap for the leg openings and the waist openings, and because my baby is thin, i find i cant get the leg openings quite tight enough. we sometimes have wick-leaks because of this, when the onesie creeps inside the leg holes and starts absorbing. the overlap snap at the waist is perfect for getting a tight enough closure on the waist though, which is great.
