This product works just as advertised!! Guitar center told me the only way to connect my mic to my computer was either an expensive converter box or a usb mic. A-HOLES haha. I love this little gizmo and would definitely recommend it to a friend!!

Go to Costco, and you can buy lower than this price per oz. Currently $32 ($3 off regular $34.99)+ tax for big size = 0.83$/oz. Besides, it is more convinient to return if you kid does not like this formula Be careful, many times some sellers over price a product, and still make the product rank in the best sellers.

Perhaps the worst bottle of wine I've ever had. I'm not even sure I would cook with this. It is thin, no body, and a transparent color not characteristic of a good pinot. The taste is just bitter - not the complexity that I expect from a pinot noir of any price. Just not what I'm looking for even in a low to mid price pinot noir. Maybe my bottle wasn't sealed well and went to vinegar - other reviews for this wine are favorable.
