New to this stock, so I did some simple research. I called my local Bed, Bath & Beyond and my local Williams Sonoma (Chicago). Both reported strong interest and strong sales. The salesperson at BBB said he owns one himself and that he and his wife use it all the time. He also said they were one of the test stores that was used to see if the product had legs about 6 months ago. He said it continues to do well. Williams Sonoma rep said they "use it all the time in the store" and nobody has returned it and it remains popular.
Obviously this evidence is purely anecdotal, but I would be interested in what others are hearing. It's one thing if this is a pure speculation play, but this company is clearly making a lot of money, and the product is still very new in the US and other markets, not to mention China. Holiday sales will be strong no matter what. Whether it has staying power remains to be seen, but the upside could be huge.
