If this is the company that offered the Diode Hair Laser Remover system, there are not enough bad things to say. IF THIS IS NOT that company, ignore the previous rating but please note the following concerning Groupon. While researching the product as described on Groupon, I noticed there were multiple cities around the country which had not only offered the same item weeks prior to the Jackson, MS, market, but they had "sold out" of the item. What should have been a simple transaction (and supposed to be birthday present for my husband), turned into a nightmare of dead-end emails, unanswered phone calls, uninformed answers when I could talk to someone and a lot of "that's not my department". If the item was unavailable due to non-FDA approval, this should have been noticed when trying to fill orders taken weeks before it was ever offered in my market; therefore, it should never have been offered in the first place. I understand that Groupon cannot guarantee the products and services it sells because Groupon acts like a broker, not a manufacturer. However, Groupon does have the responsibilty of insuring the transactions it sponsers are valid and properly handled. And if there is an issue, Groupon should act as the "middle man" it is and "go-between" to resolve the issue. All total, I believe both the supplier and Groupon dropped the ball on this one.
