    Make Compost Inexpensively

    from Greene, RI

    We purchase the Compost Sack back in June and have been filling it most of the summer. We continued to mix the contents as recommended and than we left it alone after we filled the compost sack for about 2 months. We just emptied the compost and was really really happy for what we found - nice rich compost that we plan to use in our garden in the Spring. The one thing we realized is that we should have at least 2 of these Compost Sacks so we can do this year round when one is filled we can fill the other one. We would recommend this to others.

    Portable Composter

    from Pittsburgh, PA

    A friend told my wife about this and I bought it for her. She is an avid gardener and this makes recycling the old stalks from her garden easy. WHen not being used she can just fold it up and put it in the shed.

    Great starter Composter

    from Chesterfield, VA

    We just received our compost ins sack and it is perfect for what we are trying to do. Our kids have had school projects dealing with conservation and recycling and this allowed us to get into composting at a low cost to teach our kids how to do it. Once we get the hang of it we can buy on of the more expensive units.

    Does Not Work

    from Atlanta, GA – Verified Buyer

    Almost immediately after I started using this, an animal ate right through it. It is, essentially, useless.

    good idea but not practical

    from Vallejo, CA – Verified Buyer

    If full it is too heavy to turn over or move from place to place. Contents dried out, they didn't "compost". Would not recommend.
