The 3-foot reinforced hose and the 12-inch wand offer good reach, so you can spray weeds or plants without bending too much or moving constantly. However, the sprayer isn’t designed for highly corrosive chemicals, so it’s best for water-based solutions and mild garden treatments.

It’s manual pump-powered, so you’ll need to pump it up to build pressure, which is fine for casual use but might be tiring for very large areas. The included adjustable shoulder strap and easy-fill design make it comfortable to carry and refill.
