UPDATE: I have used my Keurig K130/B130 for a couple of months now, and I continue to like it overall. I moderated the water-pouring problem by using a funnel every time I pour water. The sequence of buttons, opening hatches, and closing hatches has been a frustrating learning curve that still frustrates me because I obviously have not mastered the patterns needed to flawlessly open and close everything in the right order. The permanently printed directions down the left side of the otherwise nice silver colored design are virtually useless. The directions needing attention are governed by the lights on the right side of the machine. The directions on the left side of the machine fail to cue one in to the precise buttons/lights on the right side, coordinated with hatch opening and closings, that must be done in perfect order to achieve a finished cup of coffee or other beverage. If I miss a button for some reason, or don't open or close a hatch, all in the right coordinated order, the brew will not start, and I have to start all over again. The punctured Kcup is still useable, thank heavens, but the correct sequence of buttons and hatches must be followed. This is even more confusing because the first button to turn everything on is on the bottom, then you go to the top to do the rest from top to bottom, interspersed with the correct sequence of opening and closing hatches which is shown over on the left side that I forget to even look at. I suppose my major problem is that I insist on leaving the K-cup area and the water-fill area open to dry after use (to reduce slimy water residue and mold). Getting the two hatches to each stay open is another hilarious sequence of trial and error. For brewing, I seldom am able to press the turn-on button, add the Kcup, add water, place cup, and "brew" in that lovely order. The sections do not open or close separately without exactly correct order of use. Very frustrating and far too complicated to not be able to master this sequence in a couple of days. Come on, Keurig. This is not an airplane. This is a coffee maker that is supposed to have the simplicity of one-cup use of ever-so-convenient Kcups. It would make more sense to me to begin by adding water without need for a funnel, place cup on pad, add Kcup, and press start. The silver lining that is a great improvement over the K10 is that the system will not allow "brew" to occur unless the cup is sitting on the pad. Join me in laughing if you must, but that was an issue with my K10 on more than one occasion. Brewing coffee onto the countertop was not a good start for multiple mornings. I still stand by my opinion that this is the best single-cup machine I have noticed on the market, and it is an improvement over the K10 in most areas: nice design appearance; idiot proof to require a cup in place on the pad before brewing starts; sturdy construction. More than a little room for user-friendly improvements, though. I challenge Keurig to get this right before I have to buy my third machine!ORIGINAL REVIEW: I had my Keurig K10 a year and a half before it died. Not a great length of appliance life, in my opinion. Some reviewers have commented on planned obsolescence, and I agree from my K-10 experience. The Keurig systems are my preference, however, to another brand that begins with a T because K-cups are easier to find and have such a wide selection of brands and flavors. It is much harder to find the pods for the other brand. The quality of the two brands is equal, in my opinion. The Keurig K130/B130 seems sturdier than my previous K10. It offers the same single cup of water brewing that I prefer to avoid aging, slimy water. As with the K10, you have to leave the water cover and the K-cup cover raised after use to allow condensation to dry. Another way to vent this area without leaving the lid gaping open all day would be a nice improvement in design. The water fill area is significantly more difficult to use than the K10. The water area lid does not lift far enough up, so tilting the cup you are using at the correct angle to pour the water without splashing on the countertop or over the rim of the blue water holder is difficult. Water that does not go exactly into the blue plastic water cup spills down into the cup holder at the bottom. While this is not much water, it is one other little aggravation to have to wipe off the cup bottom if you remove the drainer for taller cups, which is the next major problem. Cup size limits are significant. I do not use wider diameter cups. My "standard" diameter cups fit snugly in the design circumference, so it may be difficult to adjust wider diameter cups. I love my footed mugs that are 5 inches high. With the strainer in place, the max available height is 4.5 inches. Luckily, I have matching coffee cups that are only 2.75 inches high and fit well. They also are the right size for the amount of water (6 to 7 ounces) that works best with the coffee brand I prefer, Tim Hortons. Larger amounts of water produce a less luxuriously strong but smooth coffee experience. After brewing the first cup, I removed the drainer and my 5" footed mug fit fine. At that point, I remembered that I had to remove the drainer in my K-10, so it always looked a little less finely finished. Removing the drainer in the K130/B130 also detracts from the nicely finished design. I am too lazy to remove, dry, and put the drainer back in with each use. Removing the drainer in the K130/B130 puts the mug in the bit of water that splashed down from the filler. The blue filler does not seem to be adequately sealed from the other parts of the appliance, and I never had that problem with the K10. Another design flaw, in my personal opinion, is that the left side of the sleekly designed, nicely curved, silver decorative front is permanently covered, top to bottom, with the illustrated directions for use. In my opinion, this is a major eyesore in an otherwise sleek and modern design. It could be corrected by putting the directions on clear plastic, self-adhering, pull-off material. Additionally, I would prefer half the footprint size that the machine takes up on my counter. The two decorative side pieces seem to have no functional purpose other than looking nice and providing the permanent illustrated directions. Although I have a lot of kitchen counter space, I am always looking for sleek designs that take up less room and allow more counter space for food prep. The 7 x 11.5 inch footprint could function as well with a 3 x 9 inch footprint, or maybe less! Another difference from the K10 that will require getting used to is that you have to turn the machine on before you insert the K-cup pod and pour the water. Pressing brew does nothing if you insert the pod, pour the water, and then turn the power on followed by pressing the brew button. With all these negative issues, I could not give 5 stars, but I do believe Keurig is a good system for the cost. After a day and a half without morning coffee, I praise Amazon's quick, quick distribution system!!! I trust Keurig will consider some of my opinionated issues for the next spiffy new design.A smart little coffee maker!Muy buen productoAfter using the Keurig K130/B130 Brewer at a hotel I knew this was what I've been looking for. Cannot find these small ones in the stores and this model fits perfect in my kitchen as I have limited counter space. I'm not much of a coffee drinker so the single cup brewer without all the extra bells and whistles really fit the bill for me. Plus there's no water reservoir to worry about. Ordered the Keurig Cafe Cup My K-Cup Single Reusable Coffee Filter so I could use my own coffee rather than the expensive K-Cups. At this point in time I'm very pleased with the machine. I've had no plastic taste as some have mentioned, the coffee brews to the strength that suits me and its hot. Upon the first couple of brews with my own coffee in the filter I did notice the coffee was a bit watered down so I then reduced the water from 8 oz. (fill line) to 7 oz. which is just right for my taste. If you like a strong brew use less water not more coffee grounds! I think it was the 4th & 5th brew that after the coffee poured into the cup the machine popped open and spit the filter and grounds over the counter and floor. At this point I thought I had a defective machine. Next use I made sure my filter rim was free of any coffee grounds and that it was pinched tight all around for a good seal before inserting the filter. I pressed the machine top down and gave it an extra little push downward for a snug fit and at that point I felt an extra little snap. Put water in the reservoir and proceeded with the brew. It worked perfect and continues to do so. Came to the conclusion that the two times it popped open was because the top was not latched snuggly so it released prematurally under pressure. So if you have experienced the filter or K-Cup spitting out you may want to try giving the top a little extra push when closing it. Using the filter with my own coffee grounds there is a bit of sludge in the bottom of my cup but not enough to concern me. I just don't drink it. Its the simplicity of the machine that I like and the fact that I can brew just one or two cups without any clean up other than rinsing out the filter. I also purchased the Solofill Cup K3 Chrome from WalMart as I was shopping the other day. It has a better hinge on the lid and seems better made but both filters work equally as well. If you order filters just be sure you are ordering the proper one for your particular model as they are not all compatible with certain models. I would recommend this brewer to others and stress that some problems, not all, are usually due to operator error as people tend to not read instructions.UPDATE: I purchased EZ-Cup paper filters from Bed,Bath & Beyond to insert into the My K-Cup filter & Solofill Cup K3. Just had to cut the paper lid flap off. By using the paper filters the problem with coffee sludge has been totally eliminated.I love this product! It’s super easy to use and much cheaper than buying coffee out. I purchased it in July 2015 and it only just started having problems in June 2022. After 7 years of use, accumulated calcium had clogged it. I fixed it by brewing vinegar and water without a K-cup, then I flushed it out. Now it’s as good as the day I bought it.I had a larger Keurig that had a huge reservoir for water and a tank that kept water hot so you could immediately get a hot cup of coffee. Since I don't drink a lot of coffee, every time I went to make one, the water was boiled away and I had to put more water in it. Defeated the purpose of having a large reservoir. This coffee maker is so fast heating and if you have ever forgot to put the cup under the spout before brewing you will appreciate the sensor that will not start dispensing until you have placed the cup. Saved a lot of mishaps. It's compact and easy to clean and just plain cleaner since there is no stagnant water sitting in that tank.After rinsing it at least ten times and making a whole pack of tea with it I still taste a chemical aftertaste . This is the second machine I purchased with Amazon that has thus problem. The first I managed to return it relatively unscathed. Thought I try again for thus little machine for the office but looks like the same is happening again. The last time I purchased the same machine from Sears without any issue. I may be stuck again.I actually LOVE the fact that there's no water tank... no water sitting around getting microscopic plastic in it.This product makes coffee 50% of the time, I have it for a week and sometime he only boils water and never drop it on the mug. When I ask to refund they only told me they will only give me 50% of the value and make me pay the shipping back to them.exactly what was looking for. low watt coffee maker for boondocking on battery power. no need to crank generator anymore the minute you get up. great little coffee machine
