Found Your Solemate, Yet?

My dear friend (and Pi Phi love) Ashton sent me a link to this via twitter and I want to know - has anyone heard of these (I hope I'm not the only one who's missed the boat) and even better... has anyone tried them?

I want to know if they're as effective as they're made out to be!
They're called Solemates and my dad picks on me for aerating the lawn all the time, so they seem like a little bit of genius to me!
