I have owned my Porch Potty for several years. I have done ALL of the required maintenance. I have purchased the expensive Turf-Tastic odor eliminator. Using it daily. I run water on the artificial turf daily sometimes twice daily with a watering can. I have replaced the artificial turf grass. I have tried the real turf grass in hopes that it wouldn't smell so bad. I do monthly soaks of the turf grass in my bathtub with bleach to try to eliminate the urine smell. Nothing works long term. I think that the concept is good. However, the maintenance that needs to be done to keep it order free or limited is ridiculous! It's cheaper and less of a hassle to just use puppy pee pads. The Porch Potty Standard is expensive and the added accessories needed are an additional cost. I had to buy the drain bowl and that gets gross too. The Turf-Tastic odor eliminator is $31.50 plus shipping. Every time you need to buy a new artificial turf, that is recommended 1-2 times a year that costs $49.00 plus shipping. Porch Potty charges a lot for shipping. I even emailed Porch Potty with my frustrations and the rep told me to do the EXACT same things that I already have been doing since I bought it. Even more frustrating! Seems like a great idea in theory but it still needs improvement. One would think at the price that Porch Potty charges, that the plastic used on the Porch Potty and the bowl would have Microban technology. So that the plastic would not absorb the bacteria for the urine and feces. I am going to take my over $300.00 worth of smelly plastic and throw it all in the trash! Don't waste your money! I do not recommend Porch Potty, especially for long term. Very disappointed in both the product and the manner that Porch Potty customer service handled my concerns.
