I bought the Dekor plus because my other diaper pail, which has to be twisted to individually wrap each diaper, was going through FAR too many refills. Gave that one away. The Décor Plus and its refills are so much more cost effective and convenient to use. It has a continuous flow of bag, but is a giant tube rather than a thin tube, so it fills the way a normal garbage can would. Then when the pail is full, you open its door, cut and tie off the top of the bag and are ready to fill it again. This means that for, say 30 diapers, I use about 4 feet of bag tubing, with the old one I'd use at least six inches per diaper. Now, the drawback is that odour isn't trapped as well in this system because the diapers aren't sealed off. When you stick the diaper in, it allows steaming stink (yup, it steams) waft out and around the room, but that's more of a concern with the pail than the bags. I would still choose this system over any other any day of the week.
