Quality plastic drinker with straight sides so birds do not have to duck under the bulge as in other designs. We find these are the best design to use and the easiest to fill. The bowl is also wider allowing more drinking space. Made from high-quality UV stabilised plastic for long life. Also available in a 4L and 8L size.
The photo shows a 4L drinker.
Very difficult to get the green base on. Doesn't fit nicely. Otherwise good.
Not tested out yet but looks good!
