This is a scam.
You try to get out of it and you can't, no matter how many times you cancel. They keep charging and sending the product over and over, and the best thing you can get is a 30% reimbursement. They keep the other 70%. Just add up how many times they keep 70% of their victims' money!
Worse, the product doesn't work at all! STAY AWAY from this.
Bottom Line: No, I would not recommend this to a friend
