In retrospect, I wish I'd done more research on the different genies. This one requires that you push the diaper down through the opening. The problem is, you pretty much have no option but to have your hand swiping against the same plastic that the dirty diaper trails against. It's pretty gross.

In addition, the top of ours--the lid--is always coming off. The blade is iffy--it doesn't always slice the bag quickly. Overall, I'm the opposite of satisfied.
