What Customers Are Saying

The product is generally well-received, with users praising its consistent and wide spray pattern, as well as the comfortable backpack design. However, some customers have reported issues with the durability and longevity of the pump, such as it failing to build or maintain pressure or the unit breaking down after a short period of use. A small number of users also found the sprayer to be too heavy when filled to capacity. Overall, the product appears to be reliable and effective for most users, though the pump mechanism may be an area for potential improvement.

Nice backpack sprayer

This replaced a larger Stanley backpack sprayer that seized up. This one is smaller capacity, no pressure gauge (which is an unnecessary useless feature of the Stanley), this product is more manageable, and so far so good.
