GEN Ⅱ 0.2-3.5% Fertilizer Injector Automatic Chemical Liquid Dosing Pump,13.21 GPM,POM Housing,Water Powered Liquid Dispenser for Drip Irrigation Garden Greenhouse Livestock Water Well

Not consistent at all. I've used an EC meter to test the output and it's all over the map. I can't get the injector to get even close to the desired level. I can't believe I bought 3 of these pieces of junk. These will be going in the trash!

Revised review. Contacted seller and troubleshot. Unit did not work, they sent a replacement and it works out of the box. Not sure what is wrong with the first one. Revising rating. Does not work out of the box. This seems to be a pretty close copy of another brand D25R model. This seems like it should work, I disassembled and reassembled 10-15 times and still no function. It should intake chemical but does not and it should “click” as it’s doing so. Unit does not click when water is run through, only when disassembled and doing it by hand. Return window closed before I even installed it.

This may be made of plastic but it is heavy duty plastic. It’s really well made. It’s basically a more affordable version of a Dos*tron. It’s easy to plumb into my irrigation system. It does take some getting used to get the correct dosage, so I suggest doing test runs before feeding. I Love that they included replacement seals! The top is difficult to remove, which is both good and bad. It seals well and doesn’t leak. I have very high water pressure so I use a pressure regulator to protect the pump. Once this is setup and dialed in it makes feedings easy! Changes the game.

It is impossible to get this machine to work. Without instructions or any customer support, it’s too complicated to work by itself.

Never worked feeder nose cracked , don't waist your money its junk.

I got this In-Line Fertilizing Injection System to use on my lawn and vegetable gardens. It is designed to be used via, drip irrigation, sprinkler, soaker hose and direct hose. It was very easy to put together and all the pieces come included. I use it with my soaker hose on my vegetable garden and I hook it to my sprinkler system when fertilizing my lawn. This is so handy and saves me so much time. I highly recommend this product to anyone whom gardens and anyone whom loves having the perfect yard. Great product.

exactly how described and expected
