Am I allowed to return this thing with poop all over it? For one thing, you have to handle the scooping area to put a new bag on it which, as you can imagine, gets covered in poop. Also, if you have a large dog as I do, the poop is heavy enough to pull off the piece on the back that keeps the bag attached. So on my very first use I had dog doo on my hands. I was not happy. It went straight into the trash. What a waste of money!
