Whatever you do, do not assume this is a free sample. I was away on a business trip when this arrived. When I finally opened the package, it was clear that it was a full sized product, and that you were about to be charged for it if you did not reply in 14 days...I tried to return the unopened material, but it was day 16. You can not return it, even unopened. How you can even use it and see if it works in 14 days is beyone me. So, watch it, or they will bill your account for additional bottles, since you just signed up for a delivery every 30 days!!! If you have done this Cancel right away! read full review »
