Query: Don't waste your money

Save your money! Keep the bags from your grocer for free, and throw the poop in the trash. The Doggie Dooley doesn't work six months out of the year because of the cold (of course the company doesn't tell you this until you've bought it). When it does work, it does so poorly. It is a complete pain to maintain. The flimsy plastic on mine broke before the year was up where the lid hinge is. If you want to waste your money, just set it on fire.
