This Nelson Raintree Traveling sprinkler has some positive features. Built with a steel body, it appears nearly destructible. Its "traveling" feature means that once set in place and with the hose set out in the middle of the track you want watered, it will move on its own. You don't have to run out to repeatedly move the sprinkler. And the little ramp that comes with it cane be set where you want the sprinkling to end, since the sprinkler shuts off on its own when it reaches this point.
