Rated 2.0 out of 5.0 by jfdp Uneven spary pattern cutoff
I just planted sod and really wanted to like these nozzles. I have seven installed on one circuit and the throw is good (a little shorter than advertised, but not bad) and they lay down water at a nice rate. BUT the spray pattern cutoff is uneven. So if you have a nozzle set for 90 degrees the long stream overshoots by a lot, and if you narrow the pattern to keep it from overshooting, then the short and medium streams cutoff too early, so you end up with poor coverage at the edge of the pattern. I will likely start experimenting with other nozzles to get a more even pattern.

Rated 5.0 out of 5.0 by SunInSouthFlorida Best range in a pop-up sprinkler
This nozzle offers the longest range I've been able to get out of a pop-up.
Rainbird came out with the original rotary nozzle for pop-ups, which I've used frequently. However, K-RAIN seems to have improved on the process a bit.
First, unlike the Rainbird, the K-RAIN allows 80 to 360 degree adjustment. The Rainbirds come in three sizes with about 90-degrees or so (off the top of my head) adjustment in each.
The K-RAIN's also appear to have a stronger spray so that it's affected quite as badly by wind, while the Rainbirds have smaller spray jets that are more sensitive. With that said, none of these pop-up rotary's are great in wind, their intentionally designed for efficiency, which means they're typically a fairly light stream.
The best feature is the ease in which these adjust, both the spray pattern (using the orange tool) and the collar adjustment (just below the top of the nozzle) to adjust the radius.
Unlike many, these can actually hit their radius target (nearly 30' or 60' diameter) on a non-windy day as long as you are running proper pressure. With pop-ups, you don't see a lot of long-range nozzles hitting their marketing claims.
The only downside is that they're a bit expensive. About a buck or two more than the Rainbirds it seems. For me, I don't mind a couple bucks extra for the product I prefer.
The last reviewer mentioned the issue with the spray pattern. That's somewhat true, but it hasn't been an issue in my experience. In my experience, you want just a tiny bit less water on the edges because it actually creates an even distribution without overflow in the border areas.
