In my opinion this stock is a con game. It is a fad. Look at the way it came on the market during the IPO. Further, does anyone ever buy this product? I think not. Every kiosk I visit at airports has a lonely person working, selling nothing. Oh let's not forget this is a product you can buy, use and return for a full money back guarantee. Why wouldn't someone use it for 30 days, learn the language, and then return it. What a crock.
