Raindrip PC4050B 1 GPH Pressure Compensating Drippers, Drip Irrigation Emitters for Drip Irrigation Gardening System, Maintains Constant Water Flow, 50-Pack, Black

These are doing the job as expected. Easy to install and don't clog.

No hesitation about brand or price when repeat buying these.

These are some of the best drippers I have purchased. No clogs, consistent flow, and no failures.

I've gotten two packages of these drippers. The first was an Amazon return and they worked as intended. For one gallon an hour you should see a drop every few seconds. I ordered the second set and immediately I could tell something was wrong. All of them just spray water out. At first I thought it may be a pressure issue as I didn't intially have a pressure reducer hooked up and they were at the ends of the lines (due to the fact I worked outwards and had to order more) but with a 25psi reducer installed the flow was the same. I used a measuring cup to determine they're emitting anywhere from 3-4 gallons an hour. This could easily swamp and root rot a plant in a couple weeks. Nevermind your water bill will be a lot higher than you expected. I examined the new drippers and they are inconsistent with the old ones. The front of the genuine drippers reads RAIN DRIPPER, the defective ones read RAIN DRPPER, the I is missing. The defective ones are also more matte looking than the genuine ones. In the picture the defective dripper is on the left. If you get these and they're spraying water you could simply cut the timer to 15-20 minutes instead of an hour to get the same effect water wise. If you have different flow rate emitters this could be a problem. As I have good ones and bad ones I'm sending this set back to try again for a bag of legit ones.

I have used these for years, and I swear by them. They don't clog up easily, unless they're covered by dirt. I don't use anything else for slow watering.

These were used for a gravity feed system, they worked great. Don't believe they do 1 mph in this application, but they water evenly and slowly. I let run for 2 hours and plants are well watered.

Really like the rain drip drippers they are less likely to plug up than the Competition

Huge disappointment!After adding 38 of these units to a garden drip bed, I found that 10 of the drippers shot a solid stream of water. Not drops, a solid stream.After replacing the bad drippers 2 of the replacements shot a solid stream.I can't recommend these to anyone.

They all work and they all seem to put out roughly the same amount of water. They also seem to be made in a more durable, UV resistant plastic than the cheaper PRC's knock-offs.

1gph dripper, it is what it is

Good quality but had a couple bad ones in the pack

The price was great, many of the grippers worked but also there were also many that didn't.
