Great value.  Sturdy, wall packaged, and has three handy fill/drain ports.  Am using it to store water to top off my 1000 gallon patio pond.  Can pre-treat the stored water and then just gradually top off the pond using a hose attached to one of the bottom ports.  So, don't use it to actually collect rain from the downspouts (since chemicals in the shingles might harm the fish and affect the pond ecology) ... just keep it filled with water than I de-chlorinate.  I also like the fact that is is sort of urn shaped.  Fits in with the landscaping on the patio.
