Not as pictured. Flow is greatly reduced and clogging is a problem compared the pictured version.

Exactly what I need to water my trees

You'll notice that the manufacturer says these work from 20 to 40 PSI.I use these with water barrels that generate maybe 2 PSI. And they work fine.At that pressure, these are drippers, not bubblers. But if you pop them into 1/2" irrigation distribution line, you can adjust them to get a nice, rapid drip all up and down the line. Even in a low-pressure water-barrel irrigation system.These don't deliver water very fast, when used as drippers at 2 PSI. But no irrigation is fast at 2 PSI. I'm just thrilled that they work, at all, at that low pressure.I have mine set to deliver about one gallon/hour/bubbler at roughly 2 PSI. That's a lot faster than you can get out of drip tape or drip line at that pressure, so these are well-suited to spot-watering plants that need a lot of water.Nicely enough, these will also work OK -- without adjustment, which is key -- on high-pressure (e.g., 15 PSI) water. So when the water barrels run dry, I can just hook the same irrigation line up to city water and irrigate the same plants -- just a whole lot faster. It's not perfectly balanced water distribution, but it's close enough.Bottom line is that these work reasonably well at low pressure. You wouldn't necessarily guess that from the manufacturer's description.

This is somewhat bigger and better made than the equivalent Rain Bird and DIG bubblers. Has much wider range of water flow adjustment, unlike those of those two brands

Great emitters but only 46 pieces in a 50 pack. That is like every 11 packs they get to sell 12. Pretty good #s

After using many other drip system emitters for years, I have settled on using only these adjustable bubblers in my garden and flower boxes. The beauty is that each one can be adjusted according to need, and you can easily compensate for available water pressure. Clogging is not a problem, and the value of this large bag is unbeatable.

These install easily and can be adjusted for required flow Drip to a distance up to about 20 inches.If you are on a 1/2 inch sprinkler valve max. number would be about 12 on the line at house pressure 58 PSI。

I started using these years ago. Then I got mean and began using much cheaper "alternatives" - you can get a bag of a100 of the cheap ones for less than $15. Now I how realized that the cheap ones cannot be accurately adjusted down to a very low flow. These RainDrip ones can do that. The cheap ones look the same on the outside, but the inside flow control structure is different.You should be aware that any of the drippers clog up over time and the flows diminishes. So, some checking/adjustment is needed every few months.
