Quit working after 1-year warranty expired
on October 15, 2025
Posted by: GregW
Gender:Male
I loved this machine when it worked — the concept and convenience are fantastic. Unfortunately, just after the 1-year warranty expired, one of the flavour cartridge dispensers stopped working. After reading through other reviews, it seems this is a common issue.
When I contacted Ninja support, they offered only a 30% discount on a replacement machine. That’s disappointing for a product that clearly has a recurring design flaw. Ninja should stand behind their products beyond the basic warranty, and retailers should reconsider selling an item in their stores with known reliability issues.
No, I would not recommend this to a friend.

Stinks I really wanted to love this

We bought this a year ago and it was fantastic, however it now no longer works due to a design flaw. Based on online message boards this is a common issue but ninja will not help fix. Do not buy this product unless you want to fix yourself in the future
No, I would not recommend this to a friend.

Awesome product but not all that is listed is included in the starter box. Missing 2 more flavors. Machine runs really well and flavors are great for adults and kids alike.
I would recommend this to a friend!

Warning - Ninja change up!
on June 23, 2025
Posted by: bob1234
The Ninja change up is frustrating!
This was my 3rd purchase of Ninja thirsti as I love and addicted to the product, which is why I have purchased them for my vacation rentals and home property. I was a bit shocked to learn that the packaging has changed to only one water holder and 2 pods - of course the pods are a cola and lemonade that I wont ever use. my previous purchase provided 2 water holders and 4 pods that I actually would use. Sorry Ninja - perhaps if I had paid attention I would have realized the product accessories had changed so my bad. Still disappointed . Love the thirsti system

Most unreliable product I’ve ever purchased
on June 15, 2025
Posted by: Kendall
from Arizona
Gender:Female
Honestly, bought this about 1.5 years ago and used it only once every week. During the first 6 months it stopped spewing flavor. Got a replacement under the 1 year warranty. Then didn’t take the new one out of the box until a month ago…. And big shocker, won’t spew out ANY flavor. I have tried EVERYTHING ninja recommended and now my 1 year warranty is up. I have purchased so many new CO2 cannisters and 50+ new flavors to add to my debt with ninja. None of them work. Instead I’ve ALWAYS had to squeeze flavor from the packet into my kids soda water. Do NOT recommend to anyone. Waste of money

Ninja Thirsti is amazing
on May 28, 2025
Posted by: Pete
I got a Ninja Thirsti for my birthday. I have been drinking water with flavor drops for ages and tried some Ninja flavors by hand first so I knew id at least like it. The carbonation is a game changer. Easy to use, easy to clean, and gives me so many options. I honestly like the cola flavor more than diet colas(it came with it or i might never have tried it), sparkling lemonade is amazing(the same and i ordered more), watermelon/lime on a hot summer day(also ordered more), cant wait for the other flavors I ordered to show up(root beer, lemon lime, raspberry, mango, peach). Hot tip, you can buy other water drops and use empty containers to make your own creations, only way I know to get vanilla as an addon! Great product
