I've had 2 of these now for 3 years and they work really well.  The range is not quite 41 feet, but that's probably due to my water pressure. i'd say its closer to 30 at most.  another impact sprinkler i have goes a few feet further, but it's not the biggest deal.  The positives about this are that it's very solid- i've never had a problem with it not operating properly, and it seems to spray the area very effectively. Considering that they're going on 3 years now, i'd buy them all over again with no hesitation.
