I found this awhile back & thought I gotta have it. You dig a 4ft hole & insert it down in it then you scoop the poo, raise the lid by stepping on the petal & wa la. But I dont like how the poo has to sit in there. So I am cutting out the bottom & letting it fall down to the dirt where it will dissolve & adding enzymes weekly to speed it up. You could take a 5 gallon bucket w/lid, cut the bottom out, dig the hole to fit all for about $5 or $10. I think its a great idea to keep your yard clean w/o making your trash man hate you. Anyways thought I would share. I bought the real thing which my husband will have to modify because I dont like the way it is suppose to work , It is basically a bucket w/lid & no bottom. As long as its 200ft away from water sources.
