Query: Huge Waste of Money

This is by far the worlds biggest waste of money. Who in their right mind would want to go through the hassles that this system has to offer. It's time consuming, doesn't hold many diapers, and for those of us with stinky diapers looming about its such a hassle. Walk the diaper out to the trash everyday and don't waste your money on the overpriced frills and expensive refills.
