Customer Ratings & Reviews

My kitchen is slowly being taken over by Ninja appliances. This is because I have yet to find one that doesn't exceed my expectations. Short version: This coffee maker works great, is easy to maintain (so far), and is thoughtfully made. It works with ground coffee or K-Cups and is the best single-serve machine I have found. I highly recommend it! The longer version: So far in my experience Ninja makes superior coffee to other mainstream brands that cost below $200; the temperatures are perfect and the coffee tastes great. The water tank holds a great amount of water where it doesn't need refilled constantly and where it doesn't take up too much space. It is removeable so you can easily take it to the sink to refill it. The whole area where the coffee is made is easily removable and easy to clean. There is a spoon to measure coffee grounds that shows how much to use based on how big of a cup you are using. It has storage on the side of the machine. The mechanism that switches between grounds and k-cups is stored in the bottom of the machine! I don't have to find drawer/cabinet space to store it or potentially use it when I don't use the K-Cups for too long. Very thoughtful design. The drip tray can be moved to different heights to help prevent splashing. Has a removable (for easy cleaning) frother. Not something I will really use, but it is a nice touch. I honestly have no complaints. Especially for the price point of this machine.

As someone who loves coffee,I was excited to give this coffee maker a try. Right out of the box, I was impressed by the sleek design and compact size of the machine. It doesn't take up too much space on my kitchen counter compared to my old coffee maker and looks great. Setting up the machine was super easy. The instructions were clear and easy to follow, and I had it up and running in no time. I loved that the machine came with its own reusable filter cup, so I don't always have to use K-Cups. Once the machine was ready to go, I brewed my first cup of coffee. I was really surprised by how quickly the machine brewed the coffee, and how much hotter it got my coffee, than my old coffee maker. I was able to customize how I would like my coffee from classic, rich, over ice and what size of my coffee using the different settings on the machine, which was a nice touch. One of the standout features of this machine is the frother. I was pleasantly happy with how well it did stirring my coffee, and the frother on this machine is a great addition. I just recommend after using it with a cup of water to clean it off and to use washcloth to get it really cleaned. The water Tank in this coffee maker is easy to get on and off to refill and has a huge capacity. Overall, I would highly recommend the Ninja PB051 Single-Serve Specialty Coffee Maker to anyone who enjoys quick and easy single serve coffee and wants a machine that is both easy to use and doesn't take up space.

The NINJA PB51 single serve coffee maker is an excellent buy in many ways. It's well designed and like all their products that I've purchased in the past, NINJA has done an excellent job bringing this to market. What I love about it so much is that I'm going to save a lot of money on purchasing grounds instead of K cups. That makes this a great transition machine - I can use up the K cups that I have and stop buying them in favor of a much less expensive bag of coffee grounds or beans if you have a grinder. There's also the ecological benefit of not having to continually add more K-Cup plastics into the landfills and the environment. That's always been a source of apprehension when buying a coffee maker that's convenient and uses a K-Cup mechanism. Now with this unit I'm able to be very selective and only purchase K cups that are a specialty. For example, I don't typically drink decaf, but a visitor or guest might request that over a regular cup of coffee. So, I can keep a box of decaffeinated coffee K cups in the cupboard. There are many other types of drinks that come in K-Cup form, including hot chocolate or tea. These are things I would not buy in a larger quantity, however I would in K-Cup form for accommodating guests. The savings that I will realize over the course of this product’s life will easily pay for itself. A single K-Cup is usually around $0.50. I can make a single cup of coffee using the ground for $0.10. That's a big savings, and that coupled with the reduction of K cups I'm throwing away makes this a wise purchase. The design of the coffee maker is interesting. It's slender and long and has a unique look to it. I don't particularly love this design. I would have preferred a package that is more squared and not so deep front to back. This is just personal taste, the reason I would prefer a different design is this protrudes out far on my counter. If you put it into a corner that is ideal as it would use that space optimally. But that has no impact on the functionality of the unit, it's just an aesthetic taste. Speaking of taste let's talk about whether it makes a good cup of coffee. I have used this for making coffee for myself and for more than one person at a time. Even though it's a single serve unit it can make up to 24 ounces in one brewing. In those cases of larger amounts of coffee made you'll be using grounds and filling the provided coffee basket with the right amount of coffee grounds. Everyone has different tastes when it comes to how strong they want their coffee. Ninja accommodates those tastes by providing a simple push button selector for different strength brews. You can easily choose whether you want a strong cup of coffee, or a mild one. There’s even a setting to prepare a cup of iced coffee. Since this uses a reusable coffee basket, you can expect some sediment coffee to come through if you don't grind your own. This will happen to any unit besides this one that uses a reusable filter basket. There are a few choices you can make. The easiest is just to live with it and you'll have a little bit of coffee silt at the bottom of your coffee cup. If that bothers you, then you could grind your own beans like I do. Set your grinder to a course setting and the coffee grounds will not seep through the reusable filter. Another option that I use is placing a paper coffee filter inside the reusable filter. I have a lot of leftover coffee filters from an old coffee machine. It's very simple to put a paper coffee filter either inside the basket, or in between the basket and the holder. The difference in taste is indistinguishable, but the convenience of putting a filter inside the basket is that it's very easy and less messy to throw away the grounds. This is perhaps the one negative about any reusable coffee filter basket. They are a pain in the neck to clean. That is unless you use the paper filter combination as I mentioned. This is a suggestion for the designers at NINJA, you could make this one negative less of a headache by designing the lid of the coffee container for the basket to not be on a hinge but use a quick lock top instead that you can pop on and off easily. The reason that would make a big difference is if your basket is full of used wet coffee grounds it's a pain in the neck to try and hold the lid open while dumping the coffee grounds in the garbage. That usually entails hitting the sides of the garbage can, thus putting stress on the hinge. The user would need to be careful not to break the hinge. This wouldn't be an issue if they used a removable top instead. You could carefully pop off the lid from the hinge, but I don't think it's meant to do that repeatedly and you might end up weakening the plastic and breaking it overtime. So, NINJA if you're reading this, give it a thought to ditch the hinge. The taste of the coffee that comes out of the NINJA PB51 is quite good. I've had other NINJA coffee makers and have always been happy and satisfied with the way their machines brew coffee. They have the process dialed in very well and can accommodate multiple size cups without changing the quality of the brew. The reservoir of coffee water that sits on the back of the unit is nicely designed and doesn't need to be refilled very often. Speaking of the water tank, it's neat looking but would be even better and more modern looking if were lit with a blue LED. I'm going to try and “MacGyver” my own LED on the base of the unit to light up the water tank. Again, this has nothing to do with a better cup of coffee. It's just aesthetics - but would certainly look cool. In summary I'm very pleased with this coffee maker. I think they've done an excellent job designing it and giving people the option of moving away from plastic K cups. When those first came out, I think everyone was thrilled with the idea of a single serving good cup of coffee. But later we realized that these were not very environmentally friendly. There have been attempts to make biodegradable K cups, but to my knowledge none have worked out. So, NINJA has provided a very good solution! This unit allows me to use up my remaining K cups and grind my own beans instead and save quite a bit of money and feel good that I'm not adding to the number of plastics going into the earth. I highly recommend this to anyone who generally just makes coffee for themselves and occasionally for other people. I think it covers all my needs, it makes an excellent tasting cup of coffee whether I'm using the last of my K cups or making coffee from ground beans. I should mention also that while I don't normally froth my milk, this unit has a frother that swings out from the side. I've used it several times and it does exactly what it's supposed to do. I have tried frothing hot and cold creamer, half and half, and heavy cream. I like to go low carb so just a little bit of heavy cream goes a long way! The frothing attachment is easy to remove and can be thrown in the dishwasher or easily cleaned under your faucet in the sink. I probably won't use it much, but it's neat to have especially if I have company over and I can offer something a little special like a barista would. Lol! The last suggestion for Ninja engineers is to offer a “fancy” version of this (and other), kitchen appliances. This unit is mostly plastic, as most things are these days. I would be willing to pay double the amount for the same design but in stainless steel – like a high end cappuccino / espresso machine. Overall, I give this a solid Five Stars!

This Ninja didn't disappoint. Makes a great hot cup of coffee/tea. Uses ground or k cups without any problems. Like that it stores everything on the unit so you won't misplace anything and still slim enough where it doesn't take up much counter space. Worth every penny.

I've been testing the new Ninja PB051 Single-Serve Specialty Coffee Maker for about a week. I tested it using pods, coffee grounds, and the milk frother. Overall, I love it. The best feature of this machine is that it can brew regular coffee grounds in a single serving. This means that the only reason I would have to buy the pods is to avoid cleaning out the grounds filter. The grounds filter is also extremely easy to clean. Whether I use pods or the grounds filter, the Ninja always performs phenomenally. The coffee it produces consistently tastes great and comes out of the machine hotter and faster than any other single-serve coffee machine I've ever tested. If I had to choose which tasted better, I would say it was the grounds filter. The milk frother also performed well. It did a great job of heating up the milk and making it creamy. Other things I loved about the Ninja are: The water reservoir is nice and large, which reduces the amount of times I have to fill it. There is a hidden storage drawer for the filter that is not in use. The controls are extremely simple. With that said, I highly recommend the Ninja PB051 Single-Serve Specialty Coffee Maker. You won't be disappointed.

This coffee maker is a total game-changer for my morning routine! The Ninja Pods & Grounds system gives me the flexibility to use both K-Cups and my favorite ground coffee, which is a huge plus. Whether I’m in a rush or want to savor a fresh brew, it’s got me covered. The specialty brew setting is fantastic for making rich, café-style drinks at home, and the foldaway milk frother is a brilliant touch—it works like a charm for lattes and cappuccinos. I also love the iced coffee feature; it brews directly over ice without watering it down, which is perfect for hot days. Setup was simple, and the sleek black design looks great on my kitchen counter. If you're looking for a versatile, reliable, and stylish single-serve coffee maker, this one is a winner. Highly recommended for coffee lovers!

I LOVE, LOVE this wonderful Ninja coffee maker!!! Best appliance I have in my kitchen. I have always had keurig’s, until the last one I bought that never worked right. Then I saw this great Ninja and decided to try it. Boy, was I delighted! Brews FAST, HOT with no mess to clean up AND to top it off ~ has an attached whipper that makes wonderful whipped topping for Lattes. To say I am sold on my Ninja, is THE understatement of the year!!! I’m hooked ~ Gimme That Thing!!! Sipping a Latte now. ☕️

As someone who has owned this Ninja coffee maker for over a year, I can confidently say it's been a great investment. The ability to use both pods and grounds gives me the flexibility to choose my favorite beans or opt for the convenience of K-Cups. The milk frother is a fantastic feature, creating smooth and creamy foam for my favorite coffee drinks. The machine itself is easy to clean and maintain, and the design is sleek and modern. If you're in the market for a single-serve coffee maker, I highly recommend giving this Ninja a try.

I'll start by saying, I absolutely love this brewer! I've had an all in one for about 3 yrs that I've been looking to replace lately. It had the frother and multiple options for brew strength or iced. But the footprint was fairly large, wide specifically. This Ninja brewer contains all options I prior had, while also adding in a permanent filter for grounds or Kcups, whichever one you aren't using stores beautifully in the side. It's also so slim, albeit a little long in depth, but this design works perfect for what I want. I rarely used my prior frother, maybe a few times a month, but it was something I still wanted and didn't want an extra piece of hardware to hide aware somewhere. This model has it flip out and just pushing the button on top it works great. This Ninja brewer has an adjustable mug deck, so as to accommodate all varying sizes of cups/travel mugs. It also has a good variation on brew size, for Kcups, 6, 8, 10, 12oz. For grounds, it does all the way up to 24oz in a single brew. It also includes a measuring spoon for your grounds that is built into the side of the machine as well. Water capacity is fantastic and easy to refill by either removing the top or the container as a whole. All this while also being easily cleanable with dishwasher safe parts, which is soooo important if you want consistently good tasting coffee. I enjoy my coffee strong, and this didn't disappoint with its "Rich" setting. You also have the ability to brew stronger 4oz shots for use in lattes/cappuccinos, as well as a specific "iced" coffee option. My only gripe is the lid to open and close does feel a bit rough to open at times, like I might pull to hard and flip it over, or push down to hard and cracks something. The puncture needles are only plastic, compared to some models being actual metal, so we'll see how it holds up from after a hundred Kcups. Hoping the motion improves, I suppose that might be the one area my prior Cafe brewer wins out, as it's mechanism used opposing leverage points to ease the closing. Overall though, this is a fantastic brewer with all the options, and you can tell Ninja put great thought into it's design/function, which I absolutely love.

I purchased this machine because i was setting up a tea and hot chocolate bar and it fit perfectly. I love that it has the slender body shape, more than the usual cup sizes, an adjustable platform for your cup to sit on so when the water dispenses it goes in the cup and not all over the counter and finally very impressed with the froth handle. What a great addition to the machine.

This single use coffee maker by Ninja is a winner. The coffee maker is a multi use unit. You can make coffee through pods. Make coffee from grounds and make specialty coffee. We are mainly a pod family and the Keurig pods worked flawlessly in the Ninja as well as an off brand pod that we buy. The coffee is nice and hot. To be honest I find this Ninja coffee maker makes coffee hotter than the Keurig machine which is a plus. Don't want to use pods? Go ahead and use the grounds option. That too works great. Simply use the brew basket and your favorite grounds. There are multiple cup size options. The coffee itself can be brewed as classic, rich, over ice or as a specialty option. Then there is a frother that is attached to the body of the coffee maker and swings away allowing you to fit the coffee maker in tight spaces. There is everything here for the coffee lover. Another genius feature is keeping all the parts onboard. The brew baskets are stored on the body as well as the measuring spoon. The large water reservoir means less frequent trips to the sink to fill it up. We are enjoying trying the specialty options because as I said we are primary pod users. Ninja makes great products. This is another one. I highly recommend.

Exactly what we wanted. Great versatility: single cup or more, grounds, pods, multiple sizes and strengths, easy to clean. Small footprint. Well thought out on-board storage for the scoop and accessories you don’t need at the moment; keeps them handy, but neatly tucked away until you want them.

Really like this coffee maker. It's narrow so it doesn't take up a lot of space on the counter top. The temperature is nice and hot and you can use a traveler mug if you remove the liquid catcher. I like you can use grounds or k cups. The flavor is good and most of the machine is dishwasher safe. It's also really fast! So this was a good buy.

Super compact and space saving, makes Coffee, Espresso, Latte's, Cappuccino and more. Easy to clean, no mess and it is even portable. We take it with us in our RV for great tasting coffee on the go. We love the size, ease of use, versatility and low maintenance. We Highly recommend it and give it 5 stars.

After having this product for about a week, I have to say I really like it! While I enjoy coffee from time to time, I appreciate the versatility of this machine. Not only can it make coffee, but it's great for tea and hot cocoa as well. Additionally, it has come in handy whenever I've needed hot water for other things such as cup noodles or instant rice. It's able to use k-cups or ground coffee easily with parts that are included. It's relatively easy to swap between the K-cup insert and the ground coffee insert with no unnecessary hassle. It is single serve which is perfect for me. Cleaning it is pretty straightforward as well. The water reservoir is removable and the system has a self-clean function which seems to mean that it runs hot water through all the inner parts and flushes it all out. No crusty coffee! haha. It also comes with a frother attachment that can be tucked away when not in use and easily removed for cleaning. You can pick different options for the drink size as well! There are 6 oz, 8 oz, 10 oz, 12 oz, 14 oz, 18 oz, and 24 oz options. There's also a setting for iced drinks which is perfect with summer just around the corner. Overall, this appliance packs a punch and is very versatile!

This is a great machine for the price. I love the size of it because it fits nicely on my countertop without taking up much space. The height fits nicely underneath the cupboard above and I’m able to lift the lid to insert the coffee pod without moving it from under the cupboard. The water reservoir is a good size and easy to fill also without having to move the machine. I love that it has the option to use your own coffee without using a pod and that function works very well. The milk froth or is easy to use and does a decent job. Overall, I have no complaints after owning this machine for about 4 months. We own several other ninja products and are happy with all of them.

This is simply the best single cup or pod brewing system I’ve ever experienced. The taste is similar to that of a brewed pot if coffee which I enjoy and prefer. I really love that you can use a K-Cup or grounds and both make a well rounded and perfect cup of coffee. The design is sleek an slim. The functionality is simplistic and the buttons are placed perfectly in my opinion. There are many options for cup size a coffee richness as well as an option for iced coffee. The milk frothing option is a sweet bonus. I love this machine and would highly recommended it.

It takes up very little space on the counter. It does so many different things, and it is very easy to use and clean. As a tip, use a disposable filter with the ground coffee. It makes cleaning the reusable pod so easy. The coffee is very hot and it's easy to control the strength. It also makes a great cappuccino or mocha. Love the built in frother. The price is very good for the value, especially if you watch for a sale. I should have ditched the better know brand years ago. The Ninja makes much better coffee.

This Ninja PB051 Single-Serve Specialty Coffee Maker is my new favorite morning go to for a steaming hot cup of coffee, tea, cocoa, or an iced coffee or tea. It took all of a few seconds to make me a cup of hot coffee. I used my favorite flavored coffee pod, and in no time had a great cup of coffee. The coffee pot has some fantastic features. One of the great things I like, is that I can use grounded coffee or the pods. Another great feature is that the tray to sit your cup is adjustable to whatever size you are using. It’s also very easy to clean and descale. It has a clean cycle on it. On the menu, you can choose different settings to brew the size of your choice, starting at 6 ounces and going up to 12 ounces. You can also choose the different brews, like classic, rich, over ice, or a specialty 4 ounce. There is a frothier built onto the side of the coffee maker that moves for when it is not in use. The bottom of it detaches so you can clean it easily. The water tank is in the back and holds up to 24 ounces of fresh tap water. This coffee maker is really great and I know I will get a lot of use out of it.

This is the best dang coffee maker I've ever bought. I feel bougie with my grinder, my frother, all the gagets aplenty. Got me feeling like Ariel with all her gadgets. Now I'm making the best dang coffee. If I want ground coffee, I can have it! If I want pods, got those, too! Best thing is no more Starbucks.
