Query: Worth the money

I like the Diaper Champ. It is easy to use and it doesn't leave my son's nursery smelling like diapers. Let's face it, this IS for dirty diapers, so there is going to be some smell, but it really is minimal. The only time I really smell the diapers is when I am changing the bag. I didn't see the point of wasting money to buy refills for the Genie. I LOVE that I can use regular kitchen garbage bags for this. The reason I gave 4 stars is because the diapers sometimes get caught in the channel that dumps into the bag. I have found that to solve this problem most of the time, just be sure that the diaper tabs are stuck to the diaper rather than left flapping.
