Ex Input:
Good quality nectar.  Very tasty.  However, I was expecting 46 fluid ounces, not 46 ounces in weight.  I find that 46 ounces in weight makes about 32 fluid ounces.

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!!

Ex Input:
Pleasant mixture of fruit tastes and the level of carbonation is refreshing.  However, I found--particularly in the initial tastes-- the drink to be too sweet. You may well enjoy it, though, since I prefer carbonated fruit drinks more on the citrus/sour end.  The over-sweetness isn't accomplished with added sugar, or non-sugar additives; the sweetness comes from the apple and grape juice concentrates, which are the top two non-water ingredients.
