Gender:Male
The only downside for this machine is you can’t open the lid with one hand it’s a little tight, everything else is great, I love it.
I would recommend this to a friend!

Electrical issues
on January 20, 2026

We have three of these and all three have had electrical issues.
Ninja was amazing at helping warranty them but you get the same model and it has the same issue. We bought one for our daughter’s apartment and she had the same issue.

Bye bye, Keurig
on January 13, 2026
Posted by: MNcoffee62
I've waited a couple months to write a review, but happy to report this machine is really performing for us. I was so dang sick of buying a Keurig machine and having it bite the dust a year or two later, even though I descaled it on schedule, etc.
I decided to take a risk and buy this machine and I'm so glad I did. I can use a k-cup or refillable k-cup or I can simply use a paper filter and brew myself a travel mug of drip coffee. I make my husband a full pot and he nurses that all day.
Yes, there's a bit of futziness swapping out the various parts depending on how you're going to brew, but it's well worth it to have so many options in one machine.
The machine even does all the descaling for you over a 75 min run, so you're not standing around pushing a descale button over and over like on a Keurig.

Lemon!! Beware!!
on January 5, 2026
Posted by: Snooze
from Pensacola, FL
Gender:Female
While this coffee pot has all the bells and whistles, it doesn’t work right. it overflows if you make a full pot 75% of the time, the delay didn’t work this morning and i woke up to a hot empty pot on the warmer. My mom was dying of cancer when i bought this, so i have no idea what i did with the receipt, so am stuck with this overpriced hunk of garbage 🤦♀️
No, I would not recommend this to a friend.

Too many parts!
on December 29, 2025
Posted by: BoringMom
from Portland, Oregon
Gender:Female
So many parts! I don't like needing to switch out the assemblies between brew types. So many parts to wash, keep track of, and store in my already busy kitchen. Missing the simplicity of my Keurig! And the water reservoir is difficult to clean, so many corners and difficult to get under the seal.
