I purchased this product for a couple of reasons.  First, with the cost of k-cups, this offered a lower price option.  Second, this allows me to used the coffee of my choice (decaf, organic, water-processed).  The first couple of times I used these, the coffee was very weak.  I opened a regular k-cup that I had to see if there was a difference in grind size from what I was using; there was not.  Then I poured the contents of the k-cup into my disposable k-cup and it would not fit.  Apparently, the disposable cups hold less coffee, which could account for the weakness.  I also noticed that the disposable cups leak around the rim, and I often get grounds in my cup.  I started packing as much coffee as I could into the cups, to where I could barely get the top on.  This made a much better cup of coffee.  However, they still leaked, there were still grounds in my coffee, and it make my Keurig run MUCH slower.  Not to mention the cleanup...  My business uses a Keurig so that all of us can brew the coffee of our choice, and we also have a couple of tea and hot chocolate drinkers.  Everytime I use the disposable cups, I have to wipe down the machine, drip tray & my cup.  I also have to clean out the interior of the cup recepticle so that the next person doesn't have to put up with my leftovers.  All in all, these were a nice idea, but the amount of work they require makes paying a little exta for the convenience of regular k-cups more attractive.  I will probably use up what I have and then go back to the regular k-cups or find a more landfill friendly solution.

I have a 11 yr old Pomimo (1/2 Pomeranian, 1/2 American Eskimo) who seems to only like human food. Although I'd love to give him human food all the time, I know it's not good for his digestive system, and it doesn't have the proper nutrients required for a dog, especially at his current age. Upon trying various brands including Blue and Call of the Wild, I couldn't justify the price in comparison to how little my dog liked the taste. After reading some positive reviews here on Amazon for Newman's, I decided to give it a go. Surprisingly, my dog started eating the food immediately after I poured some into his dish. He never does that with other dry dog food, and usually waits to eat after I've given him a nibble of everything that I eat during the day. What makes it even better is the reasonable price for the quality. Yes, I understand that organic and quality US-made food are naturally more expensive, however some of the brands charge double of Newman's and provide only half the taste. As humans, we're usually sold by the nutritious & wholesome advertisements when buying dog food, however I think its pretty important for my dog to actually like the taste of the food also. Newman's seems to be the ticket for both nutrition and taste. Will be buying Newman's as a regular!

It was bad before we open them. I saw them when we got. I did open. It had some spot green color. I did not know what it was. I was very upset. Do not buy this product.
