I've purchased this item twice. The first delivery was excellent in all respects. The sun-dried tomatoes looked and smelled great, and they tasted even better - I ate many of them straight from the bag. Unfortunately I re-ordered and the second shipment was awful. The tomatoes were over-dried, dark brown in color, and smelled burned. Worst of all they tasted horrible in everything I've tried to use them in so far. Honestly I think I'll probably throw away the rest before I have to throw away any more dinners prepared with these. A huge disappointment after my initial impression, and due to the cost of a 5 lb. bag.

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!
