Q: This tea is stale.  I have had this brand and kind of tea many times, so I know how it should taste.  It's dated Jan. 2013, but it must have been stored improperly.  It has no fragrance and no taste.  Even the teabag paper looks yellowed.  It is worse than supermarket tea.  I cherish my breakfast tea, so am very disappointed, especially having bought six boxes of this useless stuff.  I tried to give it no stars, but that's not allowed, so I gave one for prompt shipping.

A: Negative

Q: We have this model about a year now.  It hasn't worked right from the beginning.  We often had trouble closing the top.  Sometimes it doesn't work at all.  Other times it works like a charm.  When it works like a charm, it's not uncommon to find coffee grounds in the cup. It's a mess.  I bought the same model for the office. The experience was similar.  Sometimes it makes a full cup of coffee other times it doesn't.  Sometimes it won't even work at all.  We have to turn it on and off and cross our fingers. A friend reports these problems as well.  I agree with the reviewer who says, DO NOT BUY.  A waste of money for the machine,for the K-cup that couldn't be used, and an exercise in frustration. We're in the market for a different brand.  When Keurig first came out, they had the market.  They have a lot of competition now . . . which hopefully will make it easier to find a machine that works well.

A: Negative

Q: This was my second purchase of this product. The first purchase was great, but this 2nd must have been a defective batch. Most packs did not cook correctly because they were not sealed tight and opened during cooking. That caused them to burn or not cook completely. I did not send them back because I kept thinking, maybe the next one will be better, but I was wrong. There are a few packs left, but I'm hesitant about microwaving them. I will probably purchase some again, but it will not be anytime soon.
