"My husband and I love this thing. We installed it in July and it's awesome! We have two dogs and you could never tell looking at our yard. They poo, we rake it up, and into the dooley. No more awful odor from bags baking in the garbage can sitting in the hot sun! The garbage men even noticed a difference. I'm sure the neighbors are happier, too. I constantly promote this system to other dog owners.
Yes, you do have to fill it up with water once a day, but it's a septic system. Of course they depend on water. Just be sure to install you system within range of a waterhose. We turn it on to fill when we let the dogs out in the morning. By the time the dogs are done, it's almost full. We just turn the water off, and put the hose up. We add enzymes weekly. We planted flowers around the lid to avoid running it over with the lawnmower. The flowers look fantastic and well fertilized. I have no complaints with this thing. It has saved us money on those bags."
