I had high hopes for the convenience of this product.  My daughter LOVES hot chocolate. This really was a total disappointment.  I threw these kcups out.  If you use the smallest setting on your Keurig, you get 3 oz of watery hot chocolate.  Larger settings are not drinkable.  Save your money and get cocoa packets or a good tin of hot cocoa - and take advantage of the instant hot water the keurig provides.

I was a little concerned after reader some of the reviews here, but the warranty, Blue's reputation, and Amazon customer service convinced me to give it a try. And in general, I'm pretty satisfied with it. Using it with one of my Oktava MK-301 microphones I get excellent sound, no hum, and so far, excellent reliability. I'm using it with Audacity and a few other programs, none of which have any difficulty recognizing it. There were some issues setting it up initially, and I'm a bit leery about the plastic construction, but for what I paid I think it's a good value. For those thinking of using it in field recording- stick it inside a carrying bag, and tape the cable to it to prevent stressing the USB connector. You shouldn't have any problems.
