scam they sent the product 2 days before you need to cancel so you never really try it also it is very small print that tells you you need to sent it back to them within 10 day from the order date ...they are not there 24/7 as they say ... the free trial cost me $200 as they also sent me a trail of Bright Smile they are the same company ... where taking to customer service there attitudes was simply too bad we got your money
