The company has a mail out that says full gurarantee no questions ask. That is what is presented to you when your make the purchase decision. However, after you have bought the product, in their fine print the gurarantee has changed to 30days to file. Well, who can find out if their product is any good in 30 days. You might as well not buy it anyway. But the fact remains, you purchase the product under what it says in the mail out, not what their fine print says after you receive the product. The product did not work at all for me. It was worthless. Now I have spent $139.95 for nothing, for a product that does nothing for me.
