1 GPH Netafim Woodpecker Jr Pressure Compensating Dripper Emitters (35-Pack) Kit with Hole Punch Tool and Goof Plugs for Drip Irrigation Systems

All of them installed (using the yellow tool to push down makes it a heck of lot easier) in a 40 PSI system and they're all operating perfectly - except the one I dropped in muddy water before installing, had to replace that one. They ONLY operate with the black nozzle OUT. I installed one the wrong way by accident and nope, nothing came out of it - all the negative reviews that they 'dont work' obviously didnt bother to read the instructions. There is some variability on the water flow between the emitters but it's not much, with 80% of them the flow was the same, 10% were low and 10% were high. Maybe a quarter of a gallon per hour difference one way or another at the extremes. Of the 183 installed two emitters flow is quite low and will be replaced. Unknown cause, highly likely problems are from me handling them with muddy hands. The anti-drain feature is a lifesaver! I used them to for watering a 130 foot line of arborvitae with a 5 foot elevation difference between the top and bottom tree and when the water turns off they bottom ones dont leak and the pipe doesnt empty from sucking air in the top ones. This'll keep crud from getting sucked into the emitters. They're also a lot smaller than I expected, about 3/4 the size of the emitters you see in the big box stores.

Installed the drippers and they work great. Even replaced some of the older 'name brand' ones as these truly put out the stated volume (I measured). Thank you for a quality product.

I was unable to use this product with our system. The vendor gave me add'l information on how I might make changes that would affect the product's performance. Was still unable to get water thru the emitters. But, I give a 5-start rating for the great customer service - additional guidance and no-questions-asked return. Only wish I could have gotten this product to work. It is not the product that was defective. It is my older drip system .🤔

... I bought not reading all the reviews or fine print. oops. Hurried. But they LOOK like inline. ha! However, that is not why I didn't rate great. Mine have nearly all seemed to plug up after running them just a few weeks. Oh, but I LIKE that little yellow tool... Fits perfectly in my dripper plastic repair kit, and that hole punch on it is way better than my metal-tipped one. I also love the underside of the tool, where the hole is. I used it over and over to force the drippers onto the ends of T'd tubing, after my hands got horribly sore from shoving them onto the tubing without the tool. I mean, it seemed like miles and miles of tubing for my gardens. So, I did not return them, because I needed them to water. -Replaced many of them now, with inline drippers and rerouting. Under half of these drippers are still patent. I am keeping this little yellow tool forever. I run a well to water with so in all fairness, I am not on filtered city water.

Ordered three different sizes, for a ranch orchard in Texas. Solar powered water well pumps into 2500 gallon tank on concrete pad, i.e. storage is not elevated so water pressure is low. Top of tank is about 8 feet above ground so low psi pressure. None of the emitters worked, tried multiple ones of each advertised size. My conclusion is they are designed for more highly pressurized water systems. I have found that a competing brand, Raindrip, works fine at the low water pressure, so have switched to that product.

Absolute junk ... not one of the first five I installed worked ... the box was damaged and I only received 31out of the 35 I ordered ... would not buy again!!

Works well, but I was surprised at how much smaller in diameter they are than a raindrip. Not that it matters.

I installed on my mainline, but did not get a flow. One side of the emitter is a full circle the other side has a divider in the middle. I plugged the complete hole side into my 1/2 inch tubing. Maybe I don't have sufficient pressure, but I have mini sprayers located about 20 ft beyond this location that was working.

work good

I am still in the process of installing these so i cannot comment on the performance just yet. However, the listing shows a yellow colored hole punch tool while the one provided is black. It doesn't seem like a big deal but it is very frustrating knowing that if you got the advertised color you wouldnt lose the hole puncher as often because the black one blends in with the soil. Also it is tiny which doesn't help.
