Great replacement
The product is easy to install, cheaper than the big box stores. If you need a few just order a lot. They seem to run out certain times of the year.

Sprinkler
I am replacing my sprinklers with these. They work great and cover more ground than the ones I have.Very happy. Easy to install, just took some time to set up the area I wanted wet.

Works great, replaced old Orbit w/ New Rainbird
Yard has Orbits installed about 20 years ago, they are slowly dying. The Rainbird w/ the rain curtain nozzle produces a better spray pattern and has less misting on windy days, watching both side by side. I also noticed that in areas that were struggling, the new Rainbird w/ the rain currain, use it, grass greened up quickly.They cost the same as the orbits but have a significantly better spray pattern.

U can do it yourself save ton from irrigation thuggery..
excellent heads - only minor gripe is they complicate unnecessarily adjusting the flow and the radius (though its not rocket science) to figure out all adjustment.The flow is controlled by screwing with a thin narrow screw driver (or the tool if you must waste the 5 bucks its really not needed) c;lossest to nozzle/water flow (yes check your blue nozzle plastic cone is in there!) clockwise reduces stream distance while counterclockwise increases stream -warning for novices like me- IF YOU LOOSEN THE SCEEW TOO MUCH THAT IS ALSO THE WAY TO REMOVE NOZZLE AND MY WATER PRESSURE SENT IT FLYING FAR ENOUGH THAT I DDI NOT NOTICE IF FLEW OUT and thought d was broken-but a straight shot of water like hose vs. spraying flow should be obvious to folks paying more attention than me!FWIW-my quick view of how these work (you need a thin skew driver or the Rain Bird screwdriver tool) but its nothing more than smaller skew driver with flat head..- the right side slot (visible and right and below nozzle adjustment screw) I use mainly to pull up the pop up heads (and you can check the rotation levels if you desire that way. Since they comee programmed to do 180 degree watering you really need not mess with adjustments unless you need to go above 1`80 or below with the lowest skew driver access port on bottom opposite the nozzle side where clockwise increases your areas above 180 degrees and counter lowers to as low as 60...while this is not truly part of review I wish someone would have posted this for me as it might have saved me a few annoyed 5-7pm digging parties -but then again they are labeled as "Pro/high end" so they probably do not want to make it so easy that any person can swap them like the bigger heads that make the tick tick ticking noise and encase the sprinkler head (used more in smaller yards)..If you feel braver after getting one basic replaced and working- You can get different nozzles to replace standard "30" size nozzle for Lower Angle (under tree canopies or on hilly areas) , or water saving nozzles for low pressure or other lower irrigation eeed areas (they are a $1. 79 and easy to change even for a e novice like myself)..I am replacing all my 15 year old Toros of similar type (they had a dirt filter but otherwise those seem superior). I have high pressure and stuck with 3/4 inches even though the 32SAs are about 4 bucks cheaper each- refitting the plastic lines with possible leaks to them plus the versatility of these heads seems superior to the 32SAs-welcoome correction from more pros here.Next challenge-my heads did needed replacement but root cause of head leaking in base zone after cutting to next zone was the valve gasket or tired solenoid not shutting it all way-not sure yet-- to next fun step- finding a Toro valve compatible with 1999 system-not likely hard but they do not make higher end irrigation very easy for novices - do go to any decent instructional sites on web including RainBird's own site- there is much more than comes with paper insert with these in your package-and these are not much more to buy at your local HD or Ls...FWIW...but still a couple bucks less each I think here in bundled form-might try the 5000 pro ones as they seem to be same line but a notch above--will see if available at decent price...
