This companies are a SCAM. I seen this on-line ad and ordered the teeth wightening systems from these two companies. I was charged and additional 79 dollars without my permission.(from Pro Bright) I found out later that the other company was trying to charge my account 99 dollars. (Before i closed the acct) After talking with a customer service person(from Pro Bright who understood my problem and clearly wanted to reimburse me) she told me that she was sorry but there was nothing she could do and would not give me my money back due to the companies rules. (Even after i returned there product) DO NOT BUY THESE PRODUCTS!!!
