Ninja has it down with multiple possibilities… If you wanna know more, you have to read
After taking it out of the box and running some water through it first, the thing that stood out to me the most when it was all said and done is the fact that I haven’t enjoyed a truly hot cup of coffee ( for those that don’t know coffee is brewed at its finest when the temperature is roughly around 200°F ) !!! Way to go Ninja I give you two thumbs up right off the bat!!! I also like the sleek design and keeping it compact with no wasted space. Leaves more room for other things, again kudos to Ninja!!! I did have the competition at one time and I went through two machines one was a warranty replacement and they didn’t even last a whole year plus they aren’t as sleek of a design and they take up more wasted space. So if you’re looking for sleek and compact and an excellent flavor, this is definitely the product for you! Update I used the ice selection to make iced tea filled my cup full of ice added the correct amount of tea that bags that I wanted and it brewed perfect. I was afraid it was still have a little bit of a warmth to it yet it is nice ice and cold so again two thumbs up to the Ninja inventors Update: this is such a fantastic coffee maker so much better than the competition you can use K pods and as an attachment where you can use grounds or teabags and you can make iced coffee and you can make iced tea there’s just so many possibilities you can even make specialty drinks because it has a frother I mean the possibilities are endless and I just cannot give it enough credit or the inventors enough credit. It’s just awesome so if you like more than just the option of K pods with no extra features and you don’t care how long it last go with the competition otherwise that is the best choice there is hands-down. I even bought my friend one who rarely likes changes and he loves it

Brews fast and great flavor
Absolutely love this coffee maker! Ninja has always been a good brand in my experience so I decided to give it a try. The brew strength has different settings and has been very good brews. I love the attached frother, so convenient! This brews coffee fast. Love the slender look of the machine. I got the green and it looks great on the counter . Glad I tried this coffee maker, no going back to the “other” well known brand.

I love this machine!!!
I have been loving this coffee maker! I have had a favorite coffee maker for years, and it suddenly died. I agonized over a replacement, because I liked that one so much and used it several times a day. It is still made, but the reviews reflected that it is not made for durability like it was when I bought it. I absolutely love this Ninja! I generally use coffee pods, so this is right up my alley. It is so quiet! It will make a variety of sizes for ups, mugs, travel mugs, and iced coffee. One of the features I look for is the ability to brew a strong cup from a pod. The “rich” function on this machine, does the trick! It doesn’t just run water straight through the pod, so that the flavor is lacking. It puts water through the pod in increments to get as much flavor as possible. I used the “over ice” function for the first time yesterday, and it also works slowly enough to pull as much flavor as it can. It was delicious! The brew time is really short, and yet the coffee tastes wonderful, and the temperature is perfectly hot. The machine and it’s components are very easy to clean. It takes up more space from front to back, but has very slim lines and looks good on the counter. The water tank is easy to remove, clean, and fill. I know a couple of people have mentioned having an issue with “exploding pods.” I had this happen ONE time, but I immediately realized why. When you put the pod in the machine, if you just pull the lid down, it may not fully puncture the bottom of the pod appropriately. This causes the hot water to overfill the pod, and it bursts from the pressure. There is a super simple fix!! All you have to do is place the pod in the machine, and press it down, so you feel it puncture the bottom of the pod. THEN close the lid to puncture the top! That’s it! Nothing difficult or time consuming. Just press the pod down before you close the lid. Problem solved! I haven’t had any issues since! 😊 I really am enjoying the ease of use and versatility of this machine. I think it is well made, and will be used for a long time. It is sturdy, without being bulky or heavy. The materials are sleek and easy to clean. I looked at dozens of coffee makers, and read SO many reviews before I made this purchase. The comments about the potential “exploding pods” had me a little concerned, but as I said, that won’t ever be a problem for me after realizing what can cause the issue. I’m an extremely picky person when it comes to my beloved coffee maker, and this Ninja has won me over!

Leaks
My last coffee maker was the keurig duo. After 3 years it started making noises and brewing the wrong cup suzes. I searched every coffee maker for a replacement and found this ninja. I loved everything about it especially the ground coffee basket. It has an attached frother on one side and slide in basket on the other side which holds the ground coffee basket. The ground coffee scoop attaches to the side. It was packed in the ninja box in another. Everything was wrapped separately. It took a lot more time unpacking it than it did to set it up. I followed all the instructions step by step. It was actually quite easy. I flushed the water thru as instructed. Afterwards I put in a peets kcup hit go. It brewed the coffee which was surprisingly too hot to take more than a tiny sip. I really liked this machine and it came in moss green. I left for an hour. When i came back my counter was flooded with water. I immediately thought it was from my old keurig and i hadn't noticed it. I noticed to water tank only had a little bit of water in it. It still didn't click until i refilled the water reservoir and put it back on. Slowly water started seeping from underneath the machine. The water in the reservoir had bubbles. I immediately took the reservoir off and put it on a dry paper towel to look for a crack. There wasn't one and the water wasn't bubbling off the machine. The water was still coming from under the machine because it was already in there. I thought check with Amazon online. I put in the info and the reply was i can get a refund. I didn't want a refund i wanted to exchange it. Nope have to return to kolhs not whole foods or Amazon fresh right below me. I decided to check the instruction sheet again. Ah troubleshooting. There's a section on leaks. The very last scenario is if leak is coming from under the machine call customer service. I call and was pleasantly surprice how easy it was to get to talk to a person. Kellie was very personable. I explained the leaking from under the machine. The impression i got from her was this isn't a common problem we did a video chat she looked at the machine i showed her where the water was coming from. There are 2 empty holes on the bottom. I showed her i can stick my pen up into them. The other holes like those have a screw in them. There are also non skid dots on the corners. She had me put the reservoir with water back on. It took maybe 30 seconds and i said bubblesare starting to form which she was able to see. Luckily i had the dry paper towel where it was as the water began seeping out for her to see in real-time. I told her i thought it was coming thru the holes i could stick my pen into. I was on the phone with her for 30 minutes. Yes they would send me a new machine but even if i cut off the cord the needed this one back. They won't pick it up. I would have to take it the FedEx. There isn't a FedEx anywhere near me. There are a few UPS but it can't go there. They can't send the new until they get they get the defective one. It would a few weeks to get the new one. I thought shark/ ninja would want to look over the machine to find the defect. Then i thought why did i bother and go thru all of this when i can return it to amazon and reorder it. I wasted at least 30 minutes on the phone with shark ninja and didn't get anywhere while water was still leaking from under machine. I thought i was a doing a good thing in case other people were having the same problem. After reading many of the good reviews i decided to read the bad. I'm not the only one with a leaking machine. I packed everything up and put the machine and all parts back into the box to return to amazon. I was going to reorder one even tho they were out of the green before i got to return this one. In 2 or 3 days the price went way up. Now they have 3 different models of this machine. The one i had with the frother was 99.00. I think it's now 30.00. I can do without the frother i only cared about the ground coffee basket. I've been using my french press because i don't have a machine. I'm debating if i should order the one without the frother or buy a new keurig that comes with a basket for grounds. I gave 2 stars because i like the streamlined look of this and there's a place for everything built into the machine and the actual basket for ground coffee not a kcup looking thing.

Excellent Coffee Maker for Strong Coffee
When my name brand (not K) coffee maker went to the big coffee bean in the sky, I decided that $200 was a bit pricy for something that lasted only 4 years. For the most part, I grind beans and use the filter. We don't drink a lot of coffee and I like being able to customize each cup. So I went on a search for the ideal single serve coffee brewer. After trying 2 other brewers, each with problems, I decided to give Ninja the old college try. Boy, am I glad I did. My husband for the most part, drinks a regular cup of coffee with cream and sugar. I make a hot latte every day. I have a really good moka pot, but I wanted a machine capable of making a really strong cup of coffee, which doesn't seem to exist in the majority of name brands. I gave up on the big K a long time ago. I don't use the frother. Maybe one day I will. What caught my immediate attention is the large (and I mean LARGE) filter coffee holder. It holds at least 1/2 cup of coffee! It's ginormous. I use 3 scoops to 12oz water, set on "rich" for my latte, mixed with 8oz hot milk. At first I thought I did something wrong, or that it was defective. A little water came out, and it stopped. On try #3, I decided to let it sit. Sure enough, after a minute or so, it continued. (Perhaps I should have looked at the instructions first?). Lol. What it was doing was allowing the water to soak into the grounds, to extract the coffee. This is the first time in our almost 40 years of marriage, that my husband said his coffee was too strong (and he lived in Germany for 20 years). The maker automatically detects whether you have inserted the filter or kcup. The display is intuitive and easy to program. It remembers your last setting. The brewer is Ninja quality. I've owned several Ninja appliances over the years, all still going strong. If you want a regular cup of coffee, Ninja will provide. If you want a truly strong cup of coffee, Ninja will give it to you. If anyone thinks it doesn't brew a strong cup, they're either not using enough coffee, they're using the wrong blend, or they haven't tried using the filter. Also, all accessories are stored onboard. There's a nifty drawer on the right side that stores the filter or kcup holder, while your using the other. It's a very well thought out machine. The price is very reasonable.

Perfect coffee pot for Camper or small kitchen
Exactly what I was looking for. I wanted to good quality coffee pot that didn't take up much space, had a large water compartment and one that I could take on vacation when we use our Camper. I thought about buying one to leave in the camper but since we only use it a couple of times a year, kinda felt like a waste of money. Also didn't want to buy poor quality. I love this coffee pot. It does everything and solved all my problems. Brews faster the keurig I had, makes several sizes and does great Iced coffee. I love that I can switch between pods and ground coffee. Saves a ton on counter space and heavy enough not to slide around but light enough to pickup and carry to camper with ease. Great quality. Definitely recommend. Would be a great gift for any coffee lover.

REALLY GOOD, but Ninja people, see my notes... you need to fix one small but important thing....
How to write this review? The coffee it makes is amazing, way better than the $3x the cost Keurig that I owned. but also, there is a small problem that is potentially dangerous... and just annoying. I removed one star just because of this problem, and a little bit of other things... that said, glad I bought this, would buy it again. Well, for starters, and I guess this is the most important thing.... the coffee this makes is amazing. Even K-cups that I have been using for years with my high-end Keurig, now taste about 30% better!... there is depth to the flavor, like I can taste different parts of the coffee bean.... so this was the biggest surprise, I didn't expect the coffee to taste better, but it really, truly, does.... I just needed a replacement for my old Keurig... but now I have better coffee.. So... GENERAL IMPRESSIONS of the machine... CON- The photos in Amazon are a bit cooler than the unit in person. The photos make it look kind of European and sleek and weirdly cool in an artsy kinda way. The reality is, the coffee maker looks great, but it is muuuuch more apparent in person that they saved $ on the manufacturing of the plastics on the exterior of the machine... it looks and feels, for a lack of a better term... a little "cheap". Not showstopper kind of cheap.... but just enough that it subtly bugs me.. PRO- The coffee that comes from this machine is not only better, it is a little hotter, and a 12 oz cup fills faster than my Keurig by 2X. CON- This is a SMALL BUT SUBSTANTIAL problem that the Ninja folks need to fix.... It might sound like a nit pick... but it actually isn't, this is a small but important issue regarding the tray that the coffee cup sits on while the coffee is being brewed... That tray is made of two pieces, the plastic "body" of the tray, then the metal shelf that sits across the top of the tray (the metal tray that the coffee cup actually sits on during brewing).... The metal shelf is inset into the body by about an 1/8th of an inch. This means that there is an ⅛" high ledge around your coffee cup... you can accidentally snag the bottom of the full cup of hot coffee on the shelf it sits on, and launch hot coffee all over yourself and your counter. I know how petty this sounds, but it really is a thing. It could be that muscle memory is gonna spill my coffee, because the Keurig machines all have that top shelf sit ON TOP of the plastic body.... nothing accidentally snags the coffee cup when you are grabbing it. - The other CON is really a silly and small issue.... I kind of wish that the Ninja folks put a switch on the frother instead of a cleverly placed button. That on-off button is exactly where my big hands want to grab when removing or installing the frother head. So if I froth some milk, when I go to remove the frother to wash it, I all-too-often accidentally nudge that ON-button... which means that the frother starts spinning while Im trying to remove it, and launches all of the froth stuck in the spring, all over your coffee maker, pants, floor, and wall.

Great coffee maker for single servings
I’m very happy with this Ninja coffee maker. It’s easy to use, makes coffee quickly, and the single-serve option is very convenient. The coffee tastes great, and I love that it doesn’t take up much space. It’s a great choice for anyone who wants a simple and convenient coffee maker for everyday use.

Excelente cafetera, llegó rápido y funciona perfectamente
El paquete llegó muy rápido y la cafetera llegó en excelentes condiciones, con todos sus empaques originales y los instructivos completamente nuevos. Probé la cafetera desde que llegó. Encendió sin ningún problema y probé ambas opciones de preparación: café molido y cápsulas K-Cup. Las dos funcionan muy bien. Algunas cosas que recomiendo verificar si planeas comprarla: Primero, es importante hacer un primer ciclo de preparación sin café antes de usarla por primera vez para limpiar el sistema interno. Segundo, si vives en un lugar con gran altitud sobre el nivel del mar, es recomendable nivelar o ajustar la cafetera siguiendo las instrucciones del manual. Definitivamente recomiendo leer el instructivo antes de usarla.Tercero, si usas café molido, es muy importante usar molienda media para obtener mejores resultados. También es importante saber que esta cafetera utiliza cápsulas tipo K-Cup compatibles con Keurig. No acepta cápsulas Dolce Gusto ni Nescafé. Estas cápsulas tipo K-Cup se pueden conseguir fácilmente; por ejemplo, yo las encontré en HEB. En general, la cafetera funciona muy bien. Ya probé varios de los estilos de café que ofrece y todos funcionan correctamente. Es una cafetera muy versátil.La recomiendo mucho. En mi caso, el equipo llegó completamente nuevo y hasta ahora ha funcionado perfectamente. También compré el seguro de Amazon por si llegara a necesitarlo, pero hasta el momento el producto ha funcionado de manera excelente. Muy buen producto y una excelente compra.

The machine is lovely but in Britain beware.
The coffee machine is very good but beware in Britain the voltage for the machine is 120 volts and in Britain we are 240 volt. To return the machine is very costly, the cost of sending mine back was around £60. Amazon don't want to know about returning the machine, they just send you a label to print off and that's it. I can't understand why Amazon sell items on the market place that don't comply with British voltage.

¡La amo!
Es una excelente opción a bajo costo comparado con otros productos que ofrecen menos diversidad de preparaciones. Es súper fácil de usar. Ocupa muy poco espacio y realmente considero que es un plus que acepte grano molido. OJO: Si eres de México no es “tan fácil” encontrar las cápsulas con las que trabaja (a diferencia de las Nespresso que venden en todos lados), pero Amazon resuelve ✅
