Keurig K-Slim Single Serve K-Cup Pod Coffee Maker, Multistream Technology, 3 Brew Sizes, Slim and Sleek Design, 46oz Removable Reservoir, Black

This this coffee pot worked well until it didn’t, which was a very short time after purchasing it. I purchased it in March and it stopped working in October of the same year.

Excellent slim Keurig K-cup! So convenient & really great tasting coffee. I purchased the reusable stainless steel K-cups from Amazon as well. The coffee tastes really great using both K-Cups & filling the reusable stainless steel cup! I love how it fits on our kitchen counter ( see attached photo) in a perfect spot and takes very little space. There are times when I want a cup of coffee in the afternoon but my husband doesn’t! Now I can make myself a freshly brewed cup with our new Keurig K-Slim Single serve! The coffee is nice and hot as well! Love this Keurig product!

Superb Keurig for brewing a single cup of coffee or tea at a time! Perfect for single/couple's household or small office. Works exactly as described, takes up minimal space, comes in a sleek modern look, has a rather large water reservoir, and gives a quick brew time. I couldn't be happier with this purchase. Highly recommend.

This is the second one of these units we've had. I like the size, function and cost so I bought another because the first one stopped working properly, beyond just cleaning it. Unfortunately, this new one was damaged at some point. There is a crack in the water tank. The good news is that it was exactly the same as the old one, so I just swapped them.

I purchased the K-Slim to save counter space and got rid of an older working Keurig. I gave the K-Slim the benefit of the doubt, but it failed to perform properly. FIRST THE GOOD There are no bells and whistles such as temperature control, brew strength, power on timer, etc. This is in the product description, user manual and reflected in the selling price. I don’t need or want bells and whistles. I am not a picky coffee drinker so the K-Slim should have worked for me. I will even drink gas station coffee. There is almost no waiting time for the brew to start even if refrigerated water is used. Insert a K Cup, select brew size, press the brew button and the brew will start in about ten seconds. From my personal experience Keurig has excellent consumer support where you can make a voice call and speak with a live person. For valid warranty claims a replacement is a no hassle, with free shipping included. NOW THE BAD **** ORIGINAL UNIT (single entry needle style) Purchased October 2020. I followed the user manual descale instructions exactly. When brewing coffee, the reservoir will brew three 12-ounce cups before the add water LED is displayed. This is normal. While in descale mode instructions say to keep pressing the brew button until the add water LED is illuminated. After the third 12 ounce cup of descale solution the add water LED did not come on. So, I pressed the brew button again and the power died and the unit would not power back on. Since the K-Slim does not have an internal water tank I suspect the unit overheated and a (should have) safety feature kicked in to prevent a possible fire. I googled my situation and found another person with the same issue. Maybe a software bug? **** WARRANTY REPLACEMENT #1 (single entry needle style) Replaced August 2021. No issues with the descale cycle. My issue is the amount of brew is gradually reduced to about two ounces less than the selected brew. 12oz selected=10 oz. 10 oz selected=8 oz. I confirmed the amount of water without a K Cip pod and using a measuring cup. See attached photos. To return the unit back to the correct water dispense I will have to run one or two descale cycles. I also cleaned the unit including needles per the user guide. The user guide says to descale every three months. To be fair a more frequent descaling may be required depending on water quality and amount of use. I use filtered tap water and we brew about four cups daily on average. I descale no more than every four weeks to return the unit back to the correct brew size. I had a couple of non K-Slim Keurigs in the past and did not have these issues. I used the Keurig brand descale solution and a third-party generic solution with the same results. After about ten months of use I could not get the unit to operate correctly. Keurig sent a second warranty replacement. **** WARRANTY REPLACEMENT #2 (newer “Multistream Technology” five entry needles) Replacement July 2022. It is now mid October 2022 and it has only been about three weeks since the last descale. My 12-ounce brew is only getting 10 ounces again. Time to descale again. **** FINAL THOUGHTS Keurig does make some good products, but the K-Slim is a dud. I assume I am not the only one with this K-Slim issue. I will not ask for another K-Slim warranty replacement. I am going to shop for another brewer. Maybe another model Keurig, maybe not. For the amount of money I spend on descale solution the K-Slim is not worth keeping. MY SPECULATION The K-Slim does not have an internal water tank as confirmed in the following quote from Keurig: “Unlike the other Keurig systems, the K-Slim coffee maker has no internal water tank. As a result, only the external Water Reservoir needs to be emptied prior to storing.” The K-Slim heats water using heating tubes as it is pumped from the external reservoir. I confirmed this by watching youtube videos showing the internal parts. I suspect the design of the K-Slim does not allow the descale solution to stay in the unit long enough to do its job. ******** UPDATE 10/25/2020 ******** The low output of my third warranty replacement is getting worse even with descaling. I purchased another brand coffee maker. Before recycling the K-Slim I removed the cover. I added a couple of photos to this review showing the heating tube and thermal switch (safety feature) I discussed in my original review. ******** End Of Update ************

This is my first Keurig, in the past I’ve used other brands. But I bought one for my daughter and after seeing how quick hers brew I wanted one for myself, so I ordered one. I like it much better than my previous one. This one is quick it starts brewing as soon as you push the button! My other one took several minutes before it would brew. The coffee taste is very fresh and rich. It’s very easy to operate. I haven’t descaled yet so not sure about that. I’ve only had this for a month so hopefully it will last as long as my old cheaper brand! It’s not the smallest but I wanted something that would hold water without me having to refill it every time. The only thing I don’t like is that when the water gets low it won’t let you brew without refilling. Even if the water tank has a full cup still left. I guess the sensor is not very good. All in all this is a great coffee maker. Arrived well packaged and on time, as described.

I am sold on multi-stream water dripping. I get my preferred strength with a good gram less coffee grounds. That saves the equivalent of a 12 ounce bag in less than a year.

Boy-oh-boy did I look and look and look for the perfect version of one of these K-cup coffee makers. And you know we picked one and it was a famous highly recognized name brand and it didn’t work out of the box. So we kept looking and decided that when it comes to a good K-cup coffee maker, the best thing to do is to go with the original and to go simple, which is what we did with this. We understand it’s one of the newer models and I’ve got to tell you it works perfectly. We’re very happy with it versus the other one that showed up DOA that had all kinds of extra features, but just didn’t work. This one works great. it doesn’t take up a lot of room on our counter the coffee taste tremendously good even if we pick 12 ounces and it’s very quiet and you couldn’t find one easier to use.
