Ecospout has two threads so it fits a lot of bottles. I use milk jugs with the funnel indoors and sprinkler outdoors. Ecospout is made from recycled plastic so it is saving our planet as well.
Eco Spouts really do work the way they are supposed to. I have several around the greenhouse to water dry plants with. And, because they are all but closed, mosquitos dont breed in them, so I dont have to worry about getting West Nile virus. They are very handy!
I bought the eco spout last year and have found it to be wonderfully useful. I turned a heavy duty vinegar bottle into a watering device that had the gentlest soft spray for seedlings! Works so well and this season Ill buy another for a distant part of the garden
