Gave it a four star and not a five because the plastic ball valves supplied strip out really really easily, making it impossible to attach a hose to the outlet of the barrel without it leaking. I'm still working on that, and I think the solution is either putting a metal 'quick disconnect' for the hose onto the plastic ball valve, or to actually glue the ball valve onto the male connector on the barrel. I may get away with a silicone adhesive that I can get loose with a heat gun. We'll see, but highly annoying to say the least. Other than that, this is a good sturdy rail barrel. I've used these two seasons now, and have added two more to make the total seven barrels. I've attached five barrels one to another with plastic tubing (see photos), with the first barrel having the downspout from the roof running directly into it. Since I live in the Western US, and we're eventually going to either have to stop letting endless numbers of people move here and put grass in front of their houses, or abandon the cities (not joking), this is worth doing since water conservation is at such a premium. This may sound 'politically incorrect', but I put this comment here because that is the number one valid reason to install rain barrels around your house. I use the water to replenish the jacuzzi and water the plants. If you live in a mosquito area, chlorinate the barrel with hypochlorite (and I mean the pool chlorinating grade hypochlorite, not the wimpy stuff they're selling these days for home use) , and you can boil the water to make it potable.
