Query: Just bad

Difficult to use: you have to bend down to operate this machinery while your baby is wiggling on the changing table. Emptying it requiers two people (one holds the genie, another garbage bag under it) and PHD. My mother in law who is babysitting my daughter still can't learn to do it. And to add to all its good features, after 7 months of use, its lid broke off. That's it. I'm buying DiaperChamp.
