We used these guys two years ago and they were awesome so we signed back up when we moved back to town this year and I was really disappointed.
Our kids play in our yard everyday so it didn't take us to long to figure out that only half the poop in the yard was getting picked up.
I think this time we only used them for like a month before calling it quits which makes me sad cause if they don't pick up the poop then I do blah :(
