Query: Sprayer did not work

After shaking the product, sprayed for about four minutes, and then the sprayer did not work. Washed it out, shook the product all with no good result. After much frustration took the sprayer off and just poured the product on a very few favorite plants. Would never buy this again, as it is useless without the ability to spray.
