Title: Best for a tree line
Review: Using on a 200’+ tree line. Work great. Haven’t had one clog up yet. The spike that goes into the line can be a little fragile and break off as you’re installing it. Out of ~100, probably 10-12 broke. A couple of those could have been prevented. Once they’re in, they’re great.

Title: durable, reliable
Review: Red color makes these emitters easy to spot in ground cover or under larger plants. We've been using these for a decade, and most of them have lasted the whole time. Be sure to buy also the little purple tool for inserting and removing the emitters--you'll save a *lot* of time and effort with that tool.

Title: 25% failure rate.
Review: Licensed contractor here. Got a few hundred of these and I’ve had a 25% failure rate on brand new systems with 25psi. Not sure what’s going on as I typically use the easy clean rain bird drips with almost 100% success. Thought I’d try these because it was a good price but now I don’t trust them.Update: There aren’t really any directions BUT if you don’t insert the pointy end of the dripper into the supply, the dripper will fail. Once I discovered this, my success was a lot better.

Title: Perfect drip waterers!
Review: These drippers, spaced along a plastic hose pipe, serve as easy auto watering, back garden on a timer, front on just a tap. This set up replaces and beats the soaker hose that the stitching failed on after seven months.

Title: Exactly the Right Amount of Water, Exactly Where You Want It, Automatically. Done.
Review: We have about 120 wine grape vines in six 70ft. rows on our Michigan Upper Peninsula farm. They are a mix of 1, 2 and 3 yr. olds. It's a hobby crop and we are trying to be cost and time efficient because we both work full time. Our first watering system was simply runs of soaker hose which proved unsatisfactory for a variety of reasons. We stumbled upon the Rain Bird drip irrigation system while wandering around at Menard's. The 1/2" main water line was quite reasonably priced at $30 something for 500 ft and the 1/4 tubing also at $8 for 100ft. I made my own ground staples out of 12ga vineyard wire) The whole system is well designed and very easy to install. Each of 120 vines required a certain amount of fiddling to get the tubing aimed where you want it but zip tying them to the stakes turned out to be the ticket. I am very impressed with the flexibility and the accurate delivery. We used these 1gph emitters, pierced directly into the main line and 1 foot of small tubing to aim the drip where it's needed. A little bit of trial and error and we discovered some necessary alterations in our plan, but nothing that really set us back---it was all quite logical once we got started with the installation. The whole system is run through a standard digital water timer---the kind used in-line with a garden hose. Pushing the emitters into the hose requires some effort and I'm glad I bought the special tool made for it---but I also found it useful to make a backing block out of a chunk of 2x4 to make that job even easier. Just slide the block under the main hose into the channel and the hose is supported and kept from flattening out as you easily poke that little guy in---(on the end of the block I cut a slot to make pushing in the ground staples easier) see the pictures. On the whole I'm very satisfied and we plan to install another system for our 3 big raised bed gardens. I recommend this system for DIYers and anyone who's a bit handy. Even on much smaller systems than mine, it seems like it would be cost effective in labor and water savings as well as over-all garden health.Note on useful life of system: My goal is to get at least 3 years out of this system, including taking it up each fall and reinstalling each spring. I'll update this review as those experiences are accumulated. So far so good though at this beginning stage.
