K-Duo Gen 1

My wife and I had been looking for a multi-purpose machine, one which makes both a carafe and a pod of coffee. I had seen this and after some investigation, we bought it.Observations:This is a basic machine which does not have a lot of features.I've read a number of reviews complaining the carafe spout design allows a few drops of beverage to spot the countertop. All one has to do is slow down when pouring. The wide spout is conducive to pouring quickly. Me, myself, I pour my coffee over the sink so any drips or drops go in it. Alternatively, a dish towel could be placed on the counter and poured over it.Keurig uses a 5 ounce cup measure for the carafe side. The carafe is 12 cups. 12x5=60, which is the exact reservoir size.READ the directions! This machine is easy to use and does exactly what it says it will do. To expect it to do X when it isn't designed to do, it is unreasonable to expect that performance. If you need a different set of features, find the brewer which has them. Don't buy it and then gripe it doesn't do something it was never designed or equipped to do.Pros:The machine does exactly what it says it will do, day in and day out.It has a 2 hour auto shut-off for the carafe side and a 2-3 minute shut off on the pod size.Easy and intuitive to use.It is simple to maintain. I descale it as needed with the Keurig solution. I descale about every 3 months. Depending on your water, you may have to descale more often, or less depending on your use.You can brew a carafe and use the pod side while the warming plate of the carafe is on. Haven't tried to brew both sides at once.It can be programmed to auto-brew at any given time, however, you must set the auto-brew function each brew cycle. This prevents the machine from automatically brewing a pre-programmed setting when the reservoir is nearly empty or empty. This is simply a safety measure.Cons:The directions which came with my machine says none of the parts are dishwasher safe. I would think for the money, a simple change of plastics composition would be in order without raising the price.The carafe glass stains easily, though it is easy to clean. The glass feels flimsy but I haven't dropped it.It doesn't come with the gold mesh filter, though it can be ordered or purchased at the grocery store.UPDATE:I've regularly descaled the machine with vinegar. Today however, I could not get the descale cycle completed, that is, without some frustration. I'd run out of vinegar and had (fortunately) 2 bottles of the Keurig descaler solution. I used the first bottle and was shocked at the amount of scale it removed. After completing the Duo instructions for descaling, I encountered 2 problems. First, the descale warning light would not go away. The second and most frustrating, is that in the carafe rinse, I would not get the full amount of required water to dispense. Instead of 12 cups, it gave me 8. I thought it was my mistake and I refilled the reservoir and tried it again, making sure I selected the 12 cup carafe amount. This time I got 2 and in the last attempt I got perhaps a few ounces. The pump made a whining, thudding noise.Spending a few minutes on Google told me the issue with no water was either the pump was out or debris in the line. I ran the second bottle of Keurig descale solution and let it sit for about 30 minutes. I then repeated the rinse instructions and this time I got the full amount of dispensed water.The descale lights did not turn off as expected. I learned there is a manual reset sequence which solves it. With the power "ON" press and hold the 8 cup and 10 cup selection buttons for about 5 seconds. Mine turned off immediately.

Bought & had delivered to a newly wed couple. They used it 4 months & it stopped working.

Absolutely essential. Even my hard to please Missus appreciates how easy it is to go between making a pot or a cup. The device heats quickly, makes either a cup or a pot (of various sizes) quickly, and it never drips when it's done brewing. The same cannot be said for the pot pitcher, the spout is poorly formed, and it does drip.

According to Keurig, their customer service informed me that they are aware of problems with this machine. The carafe leaks repeatedly every single time you pour a cup of coffee. It runs all over the counter then onto the floor. They have replaced the carafe for me several times but the result is the same.Now just a few months into purchasing this machine, it has quit working entirely. Tried to make a pot of coffee, and the machine cuts itself off with less than 1/2 cup brewed. The element shuts off too. They have replaced the machine but now into 2 days of this replacement, the carafe is leaking all over the place and the machine is cutting itself off again. I would not recommend this product. The only up-side is that they keep replacing it because they are aware of the problem. I see other reviews saying the same thing. Don't buy this unless you really like the UPS Store because you'll be there often returning this product as well as returning all the replacement parts.........Save your money.05/24/24 UPDATE. I am now on my 3rd Keurig replacement coffeemaker. They have replaced the carafe now 6 times. The Keurig rep told me "...it's not uncommon to replace the carafe 6-7-8 times..." They are fully aware of the defective products. Customer Service has been great to replace the broken parts, but you shouldn't have to replace a coffeemaker every 45 days. The machine is a great concept but they really need to review it's function. Each time, I have requested to return the defective parts but they don't want it back. I want them to see/use the product to fully understand what they are selling.08/01/2024 UPDATE I am now on my 4th replacement Keurig coffeemaker. This has been a complete nightmare!!! They are FULLY aware this product has numerous issues. The last representative told me that 'THIS PRODUCT HAS BEEN LABELED DEFECTIVE'. They still sell them. The carafe leaks like crazy, you pour a cup and it will literally spill all over the counter and down to the floor so you must make certain that you carry the pot to the sink and pour your cup there. The machine itself works about 60 days then it just simply shuts itself off. You'll get about a 1/2 cup of coffee made and then the machine stops and will not make any more. I like the concept of the machine in that it has one water reservoir that connects to the one-serve or the carafe and that is a really nice feature that I have enjoyed. However, that is about the only thing that you will like about this machine. They are aware, COMPLETELY aware that this product does not function properly. I have asked repeatedly to send these machines back so they can see for themselves how defective it is but they do not want the machines returned. Again, they are FULLY aware that these machines malfunction. The customer service insisted that this new machine "has been tested" and should work. I am not holding my breath. With all the problems that I have had, I wish I went to Walmart and bought a $20 machine off the shelf instead of dealing with this mess.
