I used this to replace an old head that wasn't rotating properly.It was fairly easy. I did the initial arc adjustment before installing it. After installing it was spraying too far. It was easy to adjust the screw to reduce the radius. I also made a small adjustment by using these directions: "Another way to reset the right arc is to unscrew the body cap counterclockwise and remove the internal assembly from the body. Once removed, rotate the nozzle turret to the right stop, screw the internal assembly back into the body with the nozzle aligned to the right side of the area you want irrigated. At this point you have realigned the right arc stop, and you can adjust the left arc to an appropriate setting."Should this die prematurely then I'll update this review.

We had a leaking head after about 15 years of use and this was an easy replacement. The nozzles are different from our old head, but it was easy to use one that gave the same coverage as the old one. Just a few minutes to get things back in working order.

Warning, if it doesn't show the "Tool" and a "Nozzle Pack" then all we get is a sprinkler head... only.Works great if all you need is to replace the head you busted plowing snow or mowing ... no need to dig up your old one as you can just screw in the head portion and you are set!. Me... I thought it was coming with all the hardware and had a tizzy fit when all I got was a loose head rolling around in a large box ... I figured someone returned them and I wound up with their returns... stripped of "Tool", "Nozzle" and Instructions.But that's all you get and if you want the whole Nozzle Kit Amazon sells it for about 2 bucks more.I'm old and not the sharpest "On-Line Shopper" so don't make my mistake and have a melt down.I love these nozzles, they take a lot of abuse but are no match for my snow plow.Respectfully,John GriffinLake Coeur d'Alene, Idaho

I had the sprinkler system installed 8 years ago. The rotors has weathered through many harsh New England weather.Most of them are still functioning fine, I replaced 3 rotors due to natural wear and tear to the rubber cap, which deteriorated and allowed small dirt particles to wedge is places it shouldn't. In turn causing the rotor to fail.Replaced 3 of 24 heads over 8 years... yes, I'd gladly stick with Hunter rotors just for that fact.The rotor can rotate 360degree, spray distance varies based on the nozzle used and your water psi level. I was able to cover about 45ft, but when I used the mist like nozzle, it dropped to about 30ft. So it's can be tweaked to whatever you need.Very happy with the product. Let's hope they last as long as the previous rotors I just replaced.

I have a few Hunter PGP ADJs that are showing their age, probably at least 10 years old. One broke so I got this Ultra to replace. Hunter is so good that their new products are backwards compatible so I didn't have to dig the old one out, I just unscrewed the to part and swapped out the internal mechanism. Took less than 5 minutes. The ultra is a lot easier to adjust. Plus I bought from Green Thumb Guy and they included nozzles and an adjustment too for free. I will be in the process of swapping out my heads since it is so easy.
