It's REALLY SLOW, moving, perhaps, 10-ft in an hour if I recall correctly. Having said this, it is effective in tracking my 3/4-inch hose. I tried to use it in conjunction with the new Miracle Grow in-lin feeding system. The latter feeds much too fast to be used in conjunction with this sprinkler. Next spring, I will try to figure out a somewhat different approach to automatically feeding my gardens. This sprinkler appears to be really built to last a lifetime and well worth the money.
