The product is very good and it works very nice and it's very easy to comprehend how to use it, but the way you have the purchase setup I feel is very misleading I signed up for the month the month payment and you took a full year out of my account I did not like that that is why I would never recommend your product to anyone want to use because you can really mess up a person and you could be taking money that they could not have to be taken at the time. You need the fix your payment process area or you will lose other customers like myself because I did report it to the Better Business Bureau cuz I did not appreciate that.
