Went to the website. All I saw were descriptions and dimensions about the unit itself. Didn't give a clue about how it works. :shakehead Under their terms and conditions it says:
8. Order Cancellation Policy: Typically orders cannot be cancelled. Any cancellation to an order after the original sale date will automatically incur 30% restocking/cancellation fee plus any shipping charges incurred. Please call ahead of time before canceling. If your order has been sent, you will be charged all of the freight costs.
9. Return Policy: We do not accept returns, exchanges or grant refunds under any circumstances, except as specified below regarding manufacturer's defects.
IMHO it sounds like it's on par with the magnet you put on your fuel line only a lot more expensive. Snake oil. Reminds me of a mail order deal I heard when I was a teenager (I'm 55). "Handy little gadget cuts your home gas bills in half". What you would get in the mail would be a pair of scissors. One of the goverment agencies came down on them and made them quit selling them. Something about mail fraud if I remember correctly.
