Query: waste of money

we bought this last year with the replacement cartridges from home depot, we tried this from May-September with no luck, looks nice but no matter where we placed it in our 1/2 acre yard, the pouch was always empty. we'll try again this year since we still have cartridges left but to us it's a complete waste of the $99.00 plus extra cartridges that we spent.
