After owning version one and the single use Keurig, this was eye opening to me. There are several cup sizes: 4 oz, 8 oz, and 10 oz. and I am especially impressed with the “strong” option. I keep the water tank full and refill every couple of days so it’s as easy as a button for a fresh cup of coffee in the morning. I also really enjoy the carafe and can brew a pot of coffee of 4-5 cups. It gives me the option to brew single serving or for bigger parties. This was life changing.

I wanted to love this product- especially for what I paid for it, but I don’t. I don’t hate it, but it’s not love. Not even by a long shot. It runs out of water every other day. It’s HUGE. If you don’t have much counter space this is not the brewer you want. I have had to call in and troubleshoot this thing at least 3 times. Even now it only works sometimes. It’s too expensive for it to not work. I don’t recommend it.

We absolutely love this machine! We upgraded to this from our 2.0 and absolutely love it. This machine is a beast, it makes our coffee very fast and is extremely easy to clean which I love. It is easy to operate and the instruction booklet is also easy to understand. I would highly recommend this product.

I receive this as a Christmas gift 2 years ago and dont know how I have ever lived without it. I make tea with the hot water setting, I can make individual cups of coffee or a whole tub of it with the adjustable k-cup size and the container it comes with. Easy to refill and even lets you know when its time to do so. Filters are affordable and last 6 months. You can usually pick up a pack of 2 and last all year. I keep mine on power saving mode so those who are thinking about getting one but afraid of the "always on sucking my power" aspect, don't shy away from this. You'll love it.

I LOVE LOVE LOVE my Keurig! For only two people in the house it is perfect. We were wasting so much coffee when we would use a traditional coffee maker and would make a whole pot of coffee. The Keuirg is also super easy to clean and doesn't take up too much space!

Probably our favorite machine in our whole house. So easy to use. Who wants to actually make coffee in the morning when you’re basically a zombie. This does all the work. Just pop in a k cup and press the button. So easy to use. Easy to keep clean. I have no complaints

Loved this when we got it about two years ago... The past 6 months it keeps giving the "oops" message...I call Keurig thet said that the 2.0 is discontinued that I have to buy a new one. Spent almost $200.00 on this for it to not last... Very disappointing!

This product is great after about a year. I had this for two years, and I quickly got tired of not having a warmer for the coffee in my carafe if I made a bigger batch of coffee that morning. The taste of the coffee also seemed to be altered when using reusable k-cups, even after a thorough cleaning. It is convenient if you are a one and done coffee drinker, but terrible otherwise.

Perfect coffee maker! We use it multiple times a day. It’s perfect for a single cup, as well as making a full pot using the carafe. Yeah u can purchase the kcups, or the reusable ones as well as a reusable carafe cup. Well worth the money!!!

Do I have to buy just the Keurig K cups? Can I use generic brands?

How long does it take to figure out how the machine operates? How long before you get the hang of making coffee from the maker every morning?
