Keurig K-Duo Single Serve K-Cup Pod & Carafe Coffee Maker, with Multiple Brew Sizes, 60oz Removable Reservoir, Programmable Auto Brew Carafe, (Gen 1), Black

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.

I really like this coffee maker.The convenience of pot or k-cup is great.I would definitely buy this again, BUT.....The things that need improvement.1) The display being on the top is not preferred. It should be on the front where it is easily seen by everyone. My wife is just a little over 5' and it can be tough for her to see the display.2) As several other reviewers noted; the pot "leaks or drips" when pouring. I couldn't figure this out at first, as it didn't do it every time I poured a cup of coffee. But, after some investigation, I discovered that there is a plastic "dam" under the lid that has a hole in it to let coffee pour through the spout. That's fine, but If you tip the pot too much that coffee goes over the top of the "dam" it will then leak around the lid and drip. The solution is that when the pot is more than half full, you must not tip it to the point that coffee runs over the dam and drips. Kureg shoud redesign this portion of the pot so that there is a much larger "dam" under the lit to prevent this. I realize that if the "dam" is too high it would interfere with the brew drip hole in the lid, however, it could be much higher without interfering.3) It's great that there is only one reservoir for both the pot and k-cup BUT its only big enough for one pot of coffee. So, if you're like me, I set up the machine the night before to brew a full pot, the problem is that if you decide to have a k-cup or two after the pot timer is set up, there won't be enough water left in the reservoir to make a full pot. So, I must often re-fill the reservoir before going to bed. Kureg shoud have made the reservoir at least 50% larger to allow for making k-cups while still allowing enough water to remain for brewing a full pot.4) I realize that Kureg placed the reservoir at the back to keep the overall footprint of the machine compact but this requires pulling the machine out from under the overhead cabinets in order to remove the reservoir or fill it with water. I suppose that if you could place it in a spot where there were no overhead cabinets, it wouldn't be that much of an inconvenience, but my guess is that 90% or more of customers will place this in a spot that requires the entire machine be moved in order to access the reservoir.5) Programing the pot brew isn't really that intuitive, it takes a few times doing it before it becomes second nature. I think that Kureg could have made a better user interface for the settings features.OVERALL, I'm happy with this purchase.

Really like these size and operation of this coffee maker. However, after less than 5 months it has developed a leak. Every morning we wake up to puddle of water on cabinet. Very dissapointing.Update I received new replacement from Keurig very quickly. So far it works great and pleased with there customer service. We will see how well it works in a few months.
