Green Mountain "Nantucket Blend" K-Cups make a very good cup of coffee in my <a href="http://www.amazon.com/gp/product/B000AQPMHA">Keurig B-40 B40 Elite Gourmet Single-Cup Home-Brewing System</a>. This is a very smooth tasting brew that my wife prefers over the <a href="http://www.amazon.com/gp/product/B0029XDZIK">Coffee People, Donut Shop K-Cups for Keurig Brewers (Pack of 50) [Amazon Frustration-Free Packaging</a>] I generally drink in the morning.  These are good on both "Small" and "Large" cup settings as well.  Highly Recommended!  CFH

Ex Input:
Switch tastes more like chemicals than juice. I was expecting something along the lines of Orangina, instead it's closer to orange soda but without the carbonation level that makes orange soda enjoyable. For a small drink (8.3 oz), it's pretty high in calories (140). Frankly, I don't think the flavor is good enough to justify the caloric level.  Bottom line: If you're die-hard soda drinker, this might be a better option for you. If you're a die-hard juice drinker, stick to juice. If you want fizzy juice, add a little seltzer to your fruit juice.

so happy we found this online for a reasonable price.  my two dogs love this stuff and it doesn't upset their stomachs.  Plus I love that it's not made in china or something.  when you look at the food, it looks pretty close to people food. You can see real chunks of chicken and veggies.  I don't want to give my dogs any manufactured stuff but also don't have the time to make our own dog food.
