Battery Backpack Sprayer -- No Turning Back

Love this backpack sprayer. No more manuel pumping. Steady, consistent flow and ability to adjust flow. Have used for between 2 and 3 hours at a time w/o charging for weed control in yard and mulch. Rated for much longer (up to 8 hours). Wouldn't go back to manual pump backpack sprayer. Quality built. Worth every penny. Highly recommend.
