Query: Great concept, slightly flawed execution

The design elements are great. But ... the overflow hose comes with a zip-tie to attach it to the barrel. Not sufficient. Replace that with a good hose clamp. Also, the overflow hose itself is a flat piece of flex tube: doesn't open up when it needs to, due to the inner plastic adhering to itself. I will be replacing that, too.The watering hose is not held on very well--make sure you tighten the hose clamp well! It came out while my wife was using it and we had a gushing leak.Other design elements are great: screen, varmint grate, overall conception. We like it and use it with a rain chain.
