Used it to spread compost topsoil mix and grass seeds on my aerated and scarified (prepared) lawn. Saw a vid of an English chap professional landscaper using it that way. The results were phenomenal about a month later.
There a gap on one side of the door where it clasp shut. Not a deal breaker, but it makes closing the door more of a chore to align every time you load.
The product was very well constructed, easy to assemble and function as expected. I use it to sift and apply peat moss, and then soil very happy with its performance.
