I am probably among the last to applaud the benefits of this product. It flows water and/or fertilizer to the roots and is especially beneficial when I see a tree or shrub wilting from the heat. I have one that is probably 20 years old. The water flow is very strong. Since I now have a half acre lot, I thought I would order another. The current version pales by comparison. It is shorter length and the water flow is weak. Materials are poorer as well.
