Only "Approved" K-Cup = Corporate Greed
Keurig Brand Name = Mud
Yet another company ruined by bean-counters.
Looking into other brand ....

Do not buy K-Cups from this seller! The seal on the top of the K-Cup does not stay closed during the brewing process and you end up with coffee grounds in your coffee and a mess all over the counter! This is not a Keurig issue as other K-Cups work perfectly in the same machine.

The coffee tastes good if the k-cups survive puncture, but every other k-cup is exploding in my Keurig, filling my cup with coffee and grounds, which makes it taste awful. When the needle pierces the top, it breaks the foil seal around the edge. What good is tasty coffee if you can't get a grounds-free cup most of the time? It wastes money. I've never had problems with Donut House, Caribou, or Folgers. I won't buy Tully's again.

I told you Keurig folks that making a brewer that locks out others k-cups is a mistake.  Continue to do this and eventually your market will dwindle to nothing unless you free up the lockout on the 2.0 or you don't and stock of older Keurig's runs out.  Let the next challenger to your expired patents begin their quest for intelligent market dominance.

What makes you think you will transcend the very same affliction that impacted Sony with their Beta Max format which was hands down the better technology than VHS, but locked folks out by limiting titles in the Beta Max format.

There are other examples of this type of market arrogance.  Conditionally, Apple has sort of slid through this, but it is not a perfect example either.

Free market...BRING IT ON!

Tricked again by a Greedy CEO, Proprietary Green Mountain, K-Cups, or Tully's K-Cups will only work in this machine, no other ones. Sony tried this with Batteries and Accessories, look where that took them!

Stay AWAY from the 2.0 version, or buy a Mr. Coffee, Cuisinart, or a Breville machine!

Sometimes I can be a bit nave. I noticed that my K550 was not taking my old K-Cups so I called Keurig customer service to get answers. I was told that I cannot use these K-Cups so that the company could guarantee the "quality" of my coffee. I quizzed the customer service representative on what he meant by quality, then I tried again with his supervisor when I could not get a logical answer. Does quality mean better tasting coffee; Stronger or weaker coffee? This 2.0 issue was quickly becoming an intriguing mystery. The supervisor read from the same "script". I suggested to him that the word "quality" is so generic that it has become almost meaningless. Why would the Company keep throwing out the word quality without an in-depth explanation? I apologized to the supervisor for not comprehending and tried again with a different question:  What advantage does the new 2.0 Brewer have over the old one? The older machines I then discovered could take all the K-Cups. The older machines could accept the refillable cups so that I could use my favorite blends at a lower cost. The older machines are not limited by the 2.0 RFID/DRM restrictions!

It finally occurred to me that the reason Keurig switched to the 2.0 DRM restrictions was to limit the competition and increase their profits. 2.0 does not increase the quality of the coffee, but the quality of Keurigs profits. I found out too that Mr. Coffee and Hamilton Beach also manufactures K-Cup coffee makers that are also sold on Amazon.

If my fellow Amazon shoppers are interested in a more in-depth explanation of the 2.0 RFID/DRM restrictions, Peters mommy did an insightful and informative review that also describes how to circumvent the imposed restriction.

This review is for 2.0 Brewers
This brewer does not work with older k-cups and non-Keurig brands...however there is a way to get around this. There is a link that shows you how and explains why they did this.
"Keurig released its brand-restricted 2.0 machines last June, and the RFID/DRM restrictions turned out to involve a special type of proprietary ink. Although Keurig wouldn't explain the specific details of how it worked, one executive did say that it involved shining infrared light on the ink and measuring the wavelength reflected back.

Why did Keurig make the switch specifically to add restrictions and limitations to its new-model machines? At the time, Keurig executives and spokespeople said the restrictions were intended to protect ordinary consumers from whatever low-quality horrors are inherent in non-Keurig-branded beverage-pod products. Meanwhile, everybody else on the planet suggested it was because Keurig got greedy.

Keurig's patent on K-cup technology expired in 2013, which is why off-brand or refillable K-cup-style coffee pods exploded all over the market since then. That's also why Keurig's fourth-quarter results for fiscal year 2013 suggested that up to 12 percent of all coffee or tea pods brewed in Keurig machines came from unlicensed third-party sources.

So Keurig tweaked its machines to ensure that, instead of working with any properly sized pod, they could only work in the presence of special-wavelength infrared ink."

We Amazon shoppers have to stick together and keep the manufacturers honest!
Hope this helps, Ron

After reading all the horrible reviews, I cautiously replaced my five-year old Keurig with a new 2.0 K450 system, and I suppose overall I'm happy with the result.

The issue of only using Keurig-licensed K-Cups was my biggest concern, but a quick check through my stockpile, as well as at the local grocer and at my favorite Starbucks didn't reveal a problem. It may be me, but I couldn't find a single example of a cup that didn't say "Works with all brewers". Maybe I'm unusual, but I don't fill my own K-Cups...if I want to use a custom bean, I have other ways of brewing - to me, the Keurig is all about single-serve convenience, so the common complaint in all the reviews is a non-issue to me.

Still, I certainly understand people complaining about Keurig's policies...to me, I never understand why a brand like Keurig is willing to risk customer loyalty by enforcing silly licensing restrictions. My Nespresso unit does something similar, and I'm generally not a fan - and that's why I didn't upgrade to the previous Keurig Vue products. Of course, there are lots of consumer products in the same league as the Keurig from video game systems to razors...my old Motorola phone required a Motorola-branded charger - now I have an iPhone. But the Keurig 2.0 approach seems reasonable to me - all the K-cups I want to use are available, and none of them cost more as a result.

With that issue out of the way, I have to say that there are some good improvements to the brewer itself. The reservoir is larger and easier to clean. The tray detaches more easily so you can fit large cups (or the carafe - itself a good enhancement). I like the touch screen. It's quieter, and it even seems to use a bit less electricity. On the fundamentals of construction, I find it to be superior to the older units in every regard.

Of course, it's ultimately all about the quality of the coffee the machine produces, and here I think there are some improvements over the older systems as well. Especially if you like stronger coffee, the new approach seems to extract a little more flavor out of every cup.

Overall, I suppose I'm the dissenter, but I find the 2.0 product to be better than the original in every way.

DO NOT ORDER.  I recently received this order and the K-Cups have a defective seal that blows liquid out of the side all over my counter.  I do not have this issue with more expensive store bought K-Cups, so Amazon has obviously changed to a cheaper manufacturer to make it's prices.  Buyer be ware!

Update:. I'm changing my rating to one star and cancelling my "subscribe and save". I received another order with excessive grounds in every cup and it is obvious that quality control is going to be the undoing of this company. My original review was extremely positive but two orders in a row with the same problem and no response from the seller puts these k-cups in my "do not buy" file.

I have tried many K-cups and these are by far my favorite!  They are labeled as having different flavors, and they actually taste like they have flavor.  Previous coffees I have tried may be labeled as having assorted flavors, but I can't even detect the hint of any flavor other than coffee.  I have repurchased a few times and will continue to do so.  I am sticking with one brand since the other cups I have purchased are also "assorted", but it appears that I receive more of the less expensive grocery store cups versus the others.

Brews better and a little hotter than the keurig brand machines,but be careful of what coffee you buy. Does not brew some brands of k-cups. Will not brew paper filter type k-cups and k-cups that have plastic tops vs. foil. Machine does not pierce the top of plastic coated k-cups and filter paper type k- cups do not fit in the k-cup holder. All you will get is leaking water and steam. Had to give away  2 boxes of San Francisco and Mad Monkey coffee. They do not work in this machine.

I'm able to use any K-cup I want in my new Keurig. I bought the wrong version of rl the soloclip by mistake, and they were nice enough to send me the correct version.

This machine is awful. It will NOT allow you to use your v1.0 Keurig cups, and no longer allows you to brew your own coffee. Im working now actively to find an alternative, as this machine has DRM'd coffee (meaning only Keurig approved cups will be able to be brewed in it, no third party ones allowed so they can price gouge you).

I searched k cups and these came up. I ordered 30 dollars worth and now I cannot return them so I am stuck with a product I do not want.

Piece of Crap, doesn't take ALL K-Cups, only some of them...... This is where Keurig lost me. Either make a k cup unit that takes ALL kcups or don't. But please don't start making Keurig units that won't take all kcups after getting us all hooked on the kcup lifestyle........

These are knockoff K-cups, not compatible with newer models of Keurigs. I'm bummed because all the flavors sound delicious, but my Keurig 525 won't brew them.

New word for the day:  MICROGROUND.  Just Glorified Instant coffee.  K cup has No filter inside, no grounds, leaves a sediment in the bottom of your cup.  Fool me once, shame on you! You don't get any re-sales this way.  Not the brand of coffee we've come to expect after having the real deal with Keurig K Cups.  Can't believe I paid over $8 for 18 cups of instant in k-cup packages, shame on me!  If it looks like the rest, but isn't the best, you're going to get less than you expect.  If I'd realized it wasn't brewed coffee from real grounds, I never would have bought it.  It was a real eye-opener, but not from having a good cup of coffee to wake up with.

This review is for the 5 count listing Not the 2 count. Purchased these after seeing all the glowing reviews. I read through the product page and no where did I see that there would be any issue with these and the Keurig K450 2.0. But because of the useless little handles on the sides of these refillable K-Cups, the cups will not fit at all. I feel either an extensive list of models that these cups will either fit or not fit should be listed or This description should be changed "Brew & Save Refillable K-Cup for Keurig Brewers" Obviously not all Keurigs!
