I bought this not to use to catch rain water off the roof and gutter system, but out by my vegetable garden so I don't have to drag 150 feet of hose out every time I need to water.

It works really well for my purpose and I am happy with it.

One star off because when I filled it the first time it had a ton of plastic shavings from manufacturer inside.  It was a PIA to clean it all out so it did not clog the faucets.

I may update this review after I see how it does the 1st winter.  Clearly I will have to drain it because we get teps in the low 20s for weeks at a time.  But I am concerned the plastic will become brittle with the cold.  We shall see.
