[EX Q]: Although it sounded delicious, I was very disappointed in this coffee. The coffee has a strange, chemical aftertaste ... cup after cup, not just once.  Even when it brews, it creates a chemical sort of aroma.  In fact, because our single-serve pod coffee brewer was new, I started thinking the problem was the brewer.  We assumed it was a left-over manufacturing plastic or metal aftertaste coming through in the water.  I even e-mailed the coffee machine maker (Bunn) to see how to remove the aftertaste.  Imagine our surprise when a month later we opened a new pack of pods (regular Colombian, not flavored) and were delighted that our machine makes great coffee.  When we made a cup of the Senseo Vanilla again -- back came the off-taste and aroma.  Perhaps it's the "artificial flavors" used?  Be forewarned!
[EX A]: Negative

[EX Q]: I fed this to my Golden Retriever and he hated it.  He wouldn't eat it, and when he did, it gave him terrible diarrhea.  We will not be buying this again.  It's also super expensive.
[EX A]: Negative

[EX Q]: I don't write reviews at all but I'm just going to say that this is a very decent product to buy if you're not looking to spend hundreds of dollars on a mixer, phantom power supply, and pre-amp for XLR mic recording. Because guess what this little thing has it all in one all for a low price! Cop you one!
