My contractor had 2 of these when they remodeled my kitchen. He said that they use them all the time because the Bullbag is cheaper than a metal dumpster and they don't have to wait for a dumpster to be delivered. I just purchased one of these myself and filled it two weekends ago, and had it emptied Friday of last week. My contractor was right! It worked out to be 1/2 the price of what I would have paid for a dumpster!
