D O. N O T. B U Y!

Posted by: Angry Customer2KO
If I could give Z E R O stars I would! This machine is ABSOLUTELY a joke! We the people spend T O O much money on a non functional machine! I’ve only used this machine 3 times! It’s loud & make a screeching sound! The liquor gets caught in the vessel which in turn, causes M O L D! I’ve tried everything possible to fix that! I.E Waterpik, Interdental Brush, Sink sprayer. N O T H I N G works! Then HORRIBLE Customer have the audacity to tell me to purchase another vessel? WHY? Only to go through the same thing? Besides it’s ALWAYS out of stock! BEFORE Y’all SORRY engineers create ANOTHER money grabbing item, fix the issues with the previous product! Ninja corporation is a JOKE! I’m filing a claim with FDA cause MOLD IS A SAFETY ISSUE & Y’ALL DON’T WANT TO DO ANYTHING ABOUT IT! I’LL BE THE FIRST TO GET THIS STARTED!
No, I would not recommend this to a friend.

Just perfect!

I was lucky enough to get my hands on one of these before they sold out. I have made multiple different varies of slushi's and have been highly satisfied every single time. It's too easy and too convenient and use it many times a week. Easy to clean too! Best Ninja product!

FALSE ADVERTISEMENT - NO DIET DRINKS

No where in the advertisement or description does it say this WON’T work with low calorie, sugar free or diet drinks. Only found during setup. Will be returning immediately.
No, I would not recommend this to a friend.

Fun for the Whole Family!

from Gardner, KS
Gender:Female
This machine is awesome and has been a huge hit with our family. From morning coffee fun, to after school surprises and after hour adult fun we have found a use for it all day long. My kids favorite so far has been root beer floats and apple cider slushes. Love the machine, it works fast, and the clean up is so easy.
I would recommend this to a friend!

Freezes nothing at all.
on September 12, 2024

from Bandon Oregon
Gender:Female
Freezes NOTHING. Followed recipes on this site, did all the troubleshooting and the best it does is chill an already cold liquid. SO disappointed. Waited forever to get this item two days ago. I've ran it for over an hour and it will just not freeze anything. Feel pretty duped and this item is NOT cheap.
No, I would not recommend this to a friend.

Great slushi & milkshake maker!
on August 26, 2024
Posted by: DebL
from VA
Gender:Female
Bought this a couple of weeks ago. I am pleased with it so far, we have tried all of the presets, but frappé and spirit sushi have not been a success. Frappé is too foam or too icey. Tried 3 times and 3 different recipes. I was really looking forward to making my own frappé. The spirit slushi kept giving the error for not enough alcohol, but it was. I am not much of an alcohol drinker anyway. Love the slushi and milkshake though and I know my grandkids will too!
I would recommend this to a friend!

Unreachable places to clean and now growing mold
on October 6, 2024
Posted by: Shawnee91
from Texas
Gender:Female
I wanted to absolutely fall in love with this product, as I do love all things Ninja, BUT....... they fell short. I do love the idea and it does what it says and makes slushes, frappés even frozen margaritas, but where they lost 2 stars for me is the canister. When I go to clean the canister, around the edges is so thin where they glued together, you can't get in it to clean. Your drinks can though. Which is a bad combination. So after using my machine 3x, I have mold growing where I can not clean. Ninja needs to remedy this soon, before people start getting sick if they don't notice the mold. I feel like this product is extremely pricy to have this kind of oversight.
No, I would not recommend this to a friend.
