- The extra pipe to extend the spray handle is a boon and this really helped us get to reach corners and hidden areas in garden. - We fill the tank to half with water, and solution to use and pump it up to create air pressure inside. After a ten to twenty second pressure, this will hold up good inside tank and spray job runs really longer,accurate and effective. - This one gallon funner top is also easy to fill and cleaning as it has a wider mouth. - Handle really suits my usage style , ergonomic while pumping and holding up. - Spraying and flowing rates are adjustable up to half a gallon per minute. This means speed and powerful application for some of the common pesticide application. - The sprayer is multi-purpose , can be used for normal water spray to glass cleaning, foamish liquid sprays to clean car surface, weed control products, fertilizers and so on. - The poly tank is translucent and resistant also so harsh chemicals and its thickness really helps out here. My recommendation is to clean after every chemical related use and fill tank moderately, pump until adequate pressure is built and use it comfortably. Definitely durable.
