I have a Keurig and really like it. I like the variety of coffee and teas you can get. I also like that I don't have to make an entire pot of coffee to get my caffeine fix. Plus, my husband likes strong coffee and I like flavors, no more fighting or compromising.
Also, my family gets together often for dinner and all of my relatives know about my coffee maker and know where to find the k-cups. This way, if it's just Great Grandpop who wants coffee, we aren't wasting a pot.
Don't buy the cups in the store, they are too expensive. Get them online. We order them from coffeewiz.com. They have reasonable prices.
