[EX 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.
[EX A]: Negative

[EX Q]: I used to use agave nectar and honey. Even though I picked organic, there was still more sugar than desired after I put in my recipes. I actually got Tinea Versicolor due to the sugars in those products.  But this product is great. I use it in my protein shakes, smoothies, and baking recipes (muffins, breads), and it's awesome.  I make a chocolate milkshake and this stuff really rounds off the edges: - Cottage Cheese - Chocolate Protein Powder - Cacao powder - Almond Milk - Nustevia powder  Just need maybe 1/4 cup of each ingredient and 1 cup of almond milk and it takes just like a sugary chocolate milk shake.
[EX A]: Positive

[EX Q]: Okay, not like the butter most people would expect, but a very smooth, full and slightly savory vegetal flavor. The first time you take a sip, you might not notice it, but let it sit in your mouth a bit before swallowing and then take another sip. The more you drink it, the more it will become apparent. It is very soothing to the pallet.  Jin Xuan Golden Lily Oolong from Summit Tea Company it a good if not great tea, especially for the price and quantity you get. A solid every day drinker. It is not as complex as some that I've had, but that could be due to how long ago it was harvested and a number of other conditions. Depending on how you brew it, a serving of these leaves is good for 4-5 infusions before the flavor wanes, making it an even better value. And even then, the broth is soft and sweet.  If you like your Oolongs more on the green side, then you should give it a try. I know I'll be ordering another tin.
