We're sorry to read about your disappointment with Scotts Wizz Spreader and appreciate your feedback.
Make sure lock on top of handle is in unlocked (forward) position so you can fully engage the trigger. Check the Rotor Plate (green spinning thing that throws the product out to the front of the spreader). There should be a gap between the orange Edgeguard part that is directly under the hopper and the top of the cylinder portion of the green rotor plate. The bottom of the cylinder portion should be resting on the black washer like piece. Check the batteries to make sure they are in correct way (alternating directions with negative end touching spring) and there is no corrosion on the batteries or in the battery compartment. Check if you can easily manually turn the rotor plate.
