I have used flexible high density polyethylene (HDPE) tubing and fittings for irrigation sprinklers (i.e. not constant pressure) for over a year now. I haven't had any problems so far, and the connections don't seem to leak at initial installation. This connector should work for any 0.5" inside diameter flexible polyethylene pipe (funny pipe, EZ pipe, flex pipe, etc. made by Irritol, Rainbird, Orbit, Toro, and others). Caution: Most "half inch" drip line pipes are actually around 0.6" ID, so this connector will not work for most drip line applications. I base my 5 star review off of the quality of the product and the fact that I haven't had any problems. Once the flex pipe is on, I haven't been able to remove it without cutting it! I haven't had any of these fittings break, leak, or separate. However, I have used another brand that had a handle for the straight barb-fitting that did make it a little easier to install. This one is easy to use though. Just twist the pipe as you apply pressure. I noticed the orange store sells these now, and the price is identical to this online (I can't remember if there was a different price in stores). If you are doing a larger online order, I recommend finding better pricing at other online irrigation retailers. These are a great Prime add-on though. Overall, I think using flexible pipe, barb fittings, and street elbows for sprinkler heads is much better than practices that don't allow flexibility for ground movement, vehicles, people, and mowing equipment. This technique also allows more precise head placement, especially along walls, roads, and sidewalks. I use the 3/4" threaded fittings for Hunter rotor heads; you will probably want to get the elbow barb fittings as well. For spray heads, you will probably use the 1/2" threaded fittings. I attached a picture of one of my recent repairs using this item. It was a broken pipe on a flower bed zone that was recently converted to drip irrigation -- I used it as an opportunity to add in a pressure regulator and more flexibility in an area that has failed multiple times. The reviewed fitting is threaded into the bottom side of the black pressure regulator device.
