    • Position of pump handle, & weight when full
Works well for spraying weeds. Found it comfortable but heavy when full. If you're used to a heavy back pack, then there shouldn't be a problem. Well padded shoulders & hips straps.

I literally believe that there is not a single worst sprayer currently being produced anywhere in the world ... show more
