    This is a quality sprayer with excellent pressure, easy to clean, and seems very durable. I've bought a lot of sprayers over my lifetime, and I'm very happy with this one!!

    Happy with QC and Product!

    Review by on Aug 16, 2015

    Service and shipping was fast and well done. Product was exactly as described. Good sprayer! I'm glad I bought two sprayers. One for weeds and the other for creepy crawlies and lawn/garden food. I read favorable reviews on the spray and I like it much more than the other ones available on the market. Be careful to wash them out thoroughly when done and they'll keep working great for years! Just follow the instructions on use and cleaning and you'll be happy. I like the finer spray pattern than the cheaper big name hose end sprayers. August 15 2015
