There are some positive features about the Nelson Raintree Traveling Sprinkler that makes is an excellent sprinkler, and a good one to have if one has a large lawn. It's definitely sturdily built, and with a steel body, it appears nearly indestructible. Because it's a "traveling" sprinkler, once you have it set and have placed the hose in the middle of the track you want it to cover, it will move on its own and give a wide area of lawn a thorough sprinkling. One doesn't have to run out every little while to move the sprinkler so that it can water another patch of ground. Also, there's a little ramp you can run the hose through so that when the sprinkler has completed its intended course it reaches the ramp and shuts off on its own. This is particularly useful if you're not going to be around to monitor it.
