Although we havent used popins on since Chloe was about a year, I have tried the new ones, both types. The outers are nice - no bobbling and lovely colours. They work pretty much the same IMHO, great for containment, cant say the bit in the shells are a huge inprovement though or not.
One thing I'm not a fan on and wish they changed is moving the laundry tabs from the back of the nappy, annoys me to have to move chloe to the side or do it up after it's off - in case I forget. So wish they moved them to the wings like most other nappies - or just come in snaps!!
I dont like the night time booster either, it's only one layer thick and has a fleece middle bit, which is great for baby but I'm not sure why it goes around the middle of all the layers rather then just have one of the panels topped with it - the bit next to baby.
All in all they still do a great job though, not sure it's worth replacing though when you can buy new old ones for nearly half the price! Unless you really want the new colours - maybe wait for real nappy week?
I must admit I was hoping Close would do some giveaways or something for the launch but it was all a bit quite!
