I have very odd shaped beds that are hard to water without wetting sidewalks or places I don't want to get wet. I can aim the heads of the noodle anyplace I want to water. It puts out a fine stream rather than a mist so the job gets done sooner. I will be buying another for the other side of my yard. The advice to set it for a certain area and use it only for that area is very good advice, as it takes some trial and error to get it set correctly.
We got it for a historic house with a small vintage historical garden patch next to the building. Worked perfectly. No spray on the wooden building while doing a great job of soaking the plants.
This does everything I wanted it to, but the little ports clog easily from my well water. I haven't had too much success clearing them, even with a fine beading needle; whatever clogs them just rides back with the water flow. No directions on cleaning that I could find. Otherwise, I like it a lot.
We had a lot of rain this spring! And wouldn't you know it, it went from "too much" to 90+ degree and dry instantly mid-late May or thereabouts. Then I finally tried it, and was real pleased. It is my intention this year to get our act together! A dedicated sprinkler (still using a Rainbird that I loved but is off the market) and a dedicated "feeder hose" everywhere I water regularly. Which is a lot...It has a very specific usefullness. Only thing I haven't tested is to see if they last as long as my Rainbird "impulsillators". ;-) But since they aren't made of so-so plastic, I think they'll last longer. (one of the problems with the Rbird is reaching over tall plants that are close by - but the noodle can be adjusted for that.) I am disappointed that you don't have the extensions now, but I had my doubts about how well those would work. Attaching to a side of a post as suggested would probably work better anyhow.
I bought this to try in my raised beds as all other fixed pattern sprinkler heads were watering more area than was needed. You have control over direction and size of spray pattern. I love this, I'm buying another for my flower beds.
I use this in my narrow raised flower bed. A regular sprinkler was wasting lots of water. This worked perfectly.
I have several unusually shaped areas that need water! I can move the flexible noodles the directions I want to water right next to our porch and water hostas without getting the porch wet!
I liked it pretty well. The noodles are easy to bend, but I had little trouble keeping the stake at the desired angle.
