Customer Ratings & Reviews

I have this unit for 4 months and mainly use the grounds function. After using the pods adapter about 10 times, it stopped working. Although the unit was registered with Ninja, the warranty does not cover the pods adapter. This turned out to be a very poor purchase.

It’s not a Keurig that’s the one I should have bought

Quit working after a month and was told it could only be replaced once. Second one last 2 months and same thing it quit working. Junk!

Heating element died after 1 month. Best Buy has a 15 day warranty. Note to self - don’t buy anything from Best Buy!

I had for two month and its not working. Water doesn't flow and its over heating. I wanted it to return but I coudn't.

I love this coffee maker. It's as simple as it gets. The size is perfect for all living spaces, and it slides in easy onto the counter. Truthfully, we all desire to have the ultimate machine to turn our kitchen into a coffee shop. Realistically, this is not possible unless we're sacrificing other appliances. The Ninja Pods & Grounds Specialty Single-Serve Coffee Maker offers variety in the areas of size and style desired. I come from a family of coffee drinkers, and there's a division over using pods or grounds, but this accommodates for both users. Setup was very quick and easy given the slim stature of the product. After only pressing a few buttons, my coffee was ready to be brewed. I proceeded to have my first sip, and it was great. I have zero complaints because this coffee maker has made my mornings run a lot smoother. Coffee makers exists in different forms. This is a basic machine, but it's very complete. Additionally, if you have someone older who may be intimidated by modern machines then this is the perfect gift for them.

Was disappointed it wasn't working well after 2 months had to throw out

Returned as water reservoir was broken. Stood in line 25 mins as customers service shares a line with checkout.

After 2nd brew it started giving ashy/burned taste. Did cleanup couple times that flavor never went away. Can’t even return it at this point. I guess I’m stuck with it now.

Stopped working after three weeks and of course they only give you two weeks to be able to return it. I used it exactly 5 times before it stopped working completely. No refund available etc..

Stopped working after 2 weeks. Something malfunctioned with the water reservoir. Do NOT recommend.

The first time used coffee grounds went everywhere.

This was great until it stopped working several weeks later! It no longer pulls the water properly and starts to steam becoming extremely dangerous!

This is my second Ninja Coffee Maker that has broken beyond repair within a few months of purchase

This Ninja coffee maker replaces an older 10-cup model I have from a different manufacturer. The Ninja PB051 is smaller than my older model, so much so that it can sit on the countertop without any interference with the cabinet doors. As I noted above, my older coffee maker had the ability to make 10 cups at a time. It was also network aware, and showed the time and could be remotely controlled. It would also notify me when it was finished making coffee. This model can’t do any of those things. And yet, I very rarely used any of those features, with the exception of using it to show the correct time. The point being, I rarely make more than one cup of coffee at a time, so this Ninja coffee maker appears to be all I really need. I never use PODS, so I can’t speak to how well this unit performs when using PODS. I grind my own beans, so coffee grounds are my go-to method. Still, this unit supports both PODS and Grounds, and has two brew baskets specifically for those tasks. Upon receipt, my first task was running it through a clean cycle. Since this was brand new, I didn’t have to worry about emptying water from the removable 56-oz. water reservoir. I added 16oz of vinegar to the reservoir, then filled the reservoir with water up to Max line. To activate the clean cycle, press the CLEAN button once (on top of the unit), and then press the BREW button. And make sure you have a bowl that’s big enough to hold at least 56oz of liquids. The coffee maker then runs for 75 minutes going through the clean cycle. When done, the coffee maker will turn itself off. After finishing the Clean cycle, I discarded the vinegar/water mixture in the sink. I washed the reservoir out and ran a 6oz cycle of fresh water through the unit to clean out any remaining residual vinegar. Buttons used to Control the coffee maker are as follows: • Power Button • Clean Button • Style • Size • Brew The Power Button and Clean Button are self-explanatory. Style Button ---------------- This button allows you to select Classic, Rich, Over Ice, and Specialty Coffee. I almost always use the Classic option but have used the Rich on occasion if I want a more whole-body flavor. The option “Over Ice” assumes that you’ve filled your cup/mug with ice prior to making the coffee. Size Button --------------- This button lets you select how much coffee will be processed during the cycle. Please ensure that your cup’s capacity is large enough to handle your selection. At this writing, there are 7 sizes: 6oz, 8oz, 10oz, 12oz, 14oz, 18oz, and 24oz. I have a 24oz tumbler that I use, so I used it to test out the 24oz size option. It filled the tumbler up to the very top of the rim. I was certain it was going to overflow, but it stopped just in time. I guess a lesson learned is, use something that has a higher capacity than just 24oz unless you’re going to stand there and monitor its progress. How much coffee ground you use is relative to how strong you like your coffee. The instruction manual recommends the following: • Use 2-3 scoops when you’re making 6oz-12oz of coffee. • Use 3-5 scoops when making 14oz-18oz • Use 5-7 scoops when making 24oz • Use 4 scoops when making Specialty drinks. For me, I use only 1 scoop for a 6oz coffee mug. I felt the 2-scoop option was too strong for my liking. It’s all relative to what your tastebuds can handle. Remember that a scoop comes with the coffee maker, so you don’t have to purchase anything for this task. This unit also comes with a built-in, fold away Frother Whisk. Place some milk or cream into a cup and use the Frother with whip it up into a fluffy, silky topping. Spoon some out and top off your drink. I used to use the Frother on a much older coffee maker, and I enormously enjoyed enhancing my coffee drinks this way. This coffee maker comes with a permanent screened filter. After using the unit to make coffee, I had to wonder if the screened filter would allow the addition of a paper filter. Unfortunately, the documentation specifically instructs us not to do so. I like doing so because it is so much easier to dispose of the grounds, i.e., take the paper filter out and just throw it away. But, they recommend against doing that. In all, this coffee maker is pretty simple to use. It has a detachable water reservoir making it easy to fill up with water; the controls are located on top of the unit and are easy to read; and the unit comes with a spoon to help measure how much coffee grounds to use. It couldn’t be simpler. This isn’t the fastest coffee maker I’ve ever used, but it does get the job done. My only question is how long it’ll hold up to everyday use.

I just bought this this not even a month ago and it don’t work and now it says no longer refundable!!!!!!

Disappointed I had high expectations for this brand

I loved my coffee maker but after 4 months it. Stopped working

My absolute favorite coffee machine! Only one I've found that I have the option to either use a K-cup or I can brew my own coffee grounds (the filter is big enough!) I love the variety of options - 4 oz, classic, rich, over ice, with a frother... The compact size fits well on my counter and looks nice. Well priced too!
