Raindrip 122010B, 2 GPH Take-A-Part Flag Dripper, Drip Irrigation Emitters for Drip Irrigation Gardening Systems, 10-Pack, Black/Green...

This is the standard 2 gallon per hour dripper from Raindrip, not a knockoff, so they work just like you'd expect.

I have 3 acres and 10 rain drip zones for all my landscaping. I have used the heck out of all rain drip products. These are great, I can pull the top off when the water is on and clean out any clogs that might accrue. The only problem ive had is the outlet nipple can become brittle over time and break. I jut pull the broken one and install a new one, there're cheap to buy. The rain drip system saves me tons of time and water. Not a perfect product but for what it does and cost im happy.

exactly what I needed thanks

These are very good. I have purchased these before and have used them for several years. None of them have broken or become clogged with dirt, insects or other materials. They are easy to insert into the half inch and quarter inch tubing as long as you first heat the quarter inch tube in hot water for about one minute, or let the sun really heat up the half inch tubing before attempting to push the dripper into place.

This is the only kind I buy. I have small hands and arthritis, and the sharp points make it so much easier to push into the hole in the irrigation tubing. With a very long irrigation system on a 3/4 acre lot, the color coding for gallons per minute is very helpful when I see where I need to increase or decrease water flow for individual bushes. I have never had any problems with them getting clogged and the ones that have been in use for many, many years exposed to our hot desert sun, are still functioning well.
