Have another new one of these and one about 10 years old, they work better than this one, neither one of them turns themselves off, repeatedly, in the middle of watering. I complained to the seller, who referred me to Amazon, who, unlike their usual great customer service, disappointed us when they failed to respond. Husband thinks there is a defect in the shut off switch & it constantly cuts off as it rolls along it's path down the hose. I think we got a bad apple, we love the other 2 that we have.
