I was part of a test group for the Diaper Genie II and almost instantly preferred it to the regular Diaper Genie. We really liked the design compared to the original which we described as a nuclear waste container. This one is much easier to use. Flip open the lid, push diaper through the clamps, close lid. That's it, no twisting. It does a wonderful job keeping odors out. It does use refills and we finished it in about the same amount of time as the regular Genie (2 to 3 weeks). The only thing that I miss with my regular Genie is the handle that allowed me to pick it up with one hand. This was great for vacuuming or just picking it up to take to the garbage can. The Genie II requires you to use both hands to pick it up. I don't know what the price is for the refills yet since I haven't seen them on the market. If they run the same price as the regular Genie, I would recommend going for the new Diaper Genie II because it is easier to use and is a better design. Hope this helps anyone looking into diaper disposal systems.
