The problem with UltraResV is that there really is no free trial. You do not receive 10 days of resveretrol for free. You only get a 10 day period of time which does not change the amount you are billed for a one month's supply of resveretrol. I cancelled after I saw my first billed charge. But unfortunately, my cancellation was done only 2 days after they had billed my card a second time. I never received the product from the second billing and it has been over a month. It is in dispute mode with my credit card company.
