Query: A pointless product

The Nelson "Pound of Rain" advertises a coverage area of 900 square feet, but even with adjustments in water pressure, we found only 9 square feet of coverage. In order to obtain the 900 square feet advertised, one would have to move the sprinkler 100 times.We found much more success with a competitor's product. Don't waste your hard-earned money.
