Twice on price and 1/2 as much product. Burnt mon
Haven't used it yet but realized that I spent a lot more money thinking this was a five gallon instead it was a gallon. so I spent twice as much money on something that I could have got Home Depot I'm pretty upset with about five of my purchases in the last few weeks. Seriously considering not even shopping at Walmart online anymore everything's cheap high priced. not worth the money
