Nope... You don't smell anything! I've been using the Diaper Genie Elite system for 3 weeks now, and I love it. I was skeptical of buying the Diaper Genie brand because I didn't want to have to purchase the bag refills, as it is a constant added cost. So, with my last child, I tried the type of diaper garbages that you get to use your own bag in them. They DO NOT hold in the odors! Therefore, you really have to pick your battle where that is concerned, and in my opinion it is worth the added cost, because they do conceal the odor. I was slightly confused about the whole "holds 250 diapers" part, until I realized you do have to empty it approximately every 50 diapers but you don't have to get a new bag refill. You just tie a knot and pull it down again. ***I highly recommend twisting the bag tightly before cutting it to avoid letting any odor out when you're changing the bag. The only reason I give it 4 stars out of 5 is because the opening is a little tight for larger diapers. I have a newborn baby, and a 2 1/2 yr old still in diapers. My older child's diapers are a size 6, and really don't fit without a struggle. Otherwise I can't complain!
