if you are just trying this out I recommend asking a friend that has some instead of buying, I had recently tried this and called to cancel a little over a month after having it absolutely did nothing to my hair but shortly after I had tried to cancel I got billed, so I then tried to call and cancel again the lady said there's nothing she could do the shipment was already sent out before I had called well shipment arrives she says I'll have to send the box back to them and then in about 3-4 weeks I will receive my money back, I decide to just keep it since they had already took the money and it was pumpkin I love everything pumpkin, but the next month after that I had been charged again I had then called in for the third time to cancel and the lady said my account had never been canceled and that I was charged for the shipment that I decided to keep so I have been charged twice for one package, today I wake up to find out my bank account is -$30 because yet again they have took money I call in for the fourth time to see why I got charged and just now find out the shipment I had decided to keep was 3 months worth supply and so I get charged 3 times, absolute bull worst company ever and I have only opened one bottle from that whole package. Absolutely not worth anyones money DONT DO IT!!!

I was nervous about purchasing an international version of this phone but I'm happy I did. I actually owned a US AT&T version prior to this model and I can confirm the following after several days of use and testing:

Although I can use the Provider Manual this was listed as an Instructor's Manual which is really what I was looking for. I was a little disappointed when it came and I saw that it was for participants not instructors.
