My girlfriend and I have been using poopy do for the last couple months. We have service for 3 dogs with text ahead notifications on a weekly bases which adds up to 15.99 a week. Haven't had any major problems with them. They have missed a couple piles, maybe twice in 2 months but nothing serious. Haven't had a tech skip out on a week. The text ahead notificationS always let us know 10-20 minutes out. A great service in the summer if the heat bothers you or you just cant stand dog poop but it does add up at the end of the month. I'd recommend for families with multiple dogs and large yards.
