My first concern was whether or not the sprayer adapter would fit the threads of my Superhandle extension pole. No problem there. Second concern was whether or not the mechanism for depressing the spray can button would fit my spray cans. Again, no problem. While the product seems overpriced, it dramatically reduces my application time, and keeps me off ladders. I would buy again.
Your product is a great tool for getting at wasp, yellow jackets and the like. Have a two story home that they love. With my recent purchase I was able to successfully remove them and protect the children. Does everything advertised.
