question:
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.
answer:
Negative


question:
Newman's Own is the best dog food ever, in my opinion. My 12 year old white German Shepard eats and digests this food wonderfully. Before changing to this food a few years ago, she had digestive problems often, even though she was fed a "so called good brand name food".  My three year old pittie girl also eats this food, and loves it .. she is in perfect health. I would recommend it to anyone. My next door neighbor orders it now from Amazon for his pittie girl. Amazon is a wonderful place to purchase dog and cat food, groceries, and anything you need .. the prices are always good, and the specials are great! The specials are the best ever, and I was shocked to find out that a today "Friday" special price on Newman's Own dog food was automatically reflected in my subscribe and save item price of the Newman's Own.  Even though I just received a bag yesterday, I ordered two more today, and some Newman's Own cat food.  What other retailer would automatically do that for you .. none that I know of.  Amazon .. please continue to offer the Newman's Own dog food .. I would be lost without the delivery, since it is difficult for me to get out and shop and carry large items like bags of dog food.  Thank you for being here for me and Snowey and Sophie.   Linda

Positive


question:
Tea helps relaxation when not boiled, try boiling water and putting two iced cubes in water before steeping. Otherwise, the kavalactones are killed by the heat.  This tea has awful stevia sweetener. Maybe I'm not just not used to it, but I don't like it. I don't want the tea maker deciding how sweet my tea should be, especially with this trash stevia.
answer:

Negative
