Title: Beyond Worthless.
Review: Believe no one who says these are worthwhile, unless of course you're interested in destroying your lawn. You see, as you walk forward your leg tips forward but the spikes DO NOT. This means that as you pull your foot the grass gets torn up as you walk forward. ALSO you'll be exhausted pulling the spikes out of the ground. In theory its a good idea...in practice its a terrible idea. Rent or hire someone to do this job.
