I first tried it with Deer Scram but it clumped and clogged. So I next tried using it to spread dry pelletized Milorganite. It jammed. Also, when filled with product, you can't set it down without risk of tipping over. So I don't know what product would work with this spreader. The Domyown customer service was great when I told them about my experience.
Bought this to use with Bifen L/P Insecticide Granules . I don't know if this is just not compatible with the Bifen granules or just poor quality overall
but it jammed with first attempt. After trying again it jammed and handle stripped off.
Might be OK for grass seed or fairy dust but pelletized herbicide, fertilizer or god forbid, rock salt will laugh at this thing.
The plastic crank spindle sheared out of the drive socket on the very first crank, spilling herbicide in a concentrated heap on a section of my lawn. Not pretty. Since it is not possible to give a zero star rating (I think) it gets a single star. Don't let that mislead you.
