I really like it, but this is the third on I’ve had. Not sure why they quit working. Ninja was great, handled it quickly and got my new one right out to me with no hassles.
I would recommend this to a friend!

Buyers Beware! Hit and Miss.

I purchased (at Costco) one box with two Ninja Blast Portable Blenders, BOTH failed the same way. It could not handle frozen fruits, ice, or bananas very well. The first blender failed after I placed an unsliced banana in the blender with almond milk, protein and peanut butter powder. (Yes, the liquid was placed first). The second blender failed after I place frozen fruit, almond milk, protein powder. Both times, the light flashed red. I poured contents out, cleaned it, tried again only to have the light flash red again. First one lasted maybe 12 blends, second one 4.
No, I would not recommend this to a friend.

Hi there,\nThank you for sharing your experience. we’re truly saddened to hear that both of your Ninja Blast blenders didn’t perform as expected. That’s definitely not the experience we want for our customers, and we understand how frustrating it must be, especially when you followed the correct blending order and still encountered issues.\nThe red flashing light typically indicates the motor is overloaded or the blade assembly is obstructed, but it shouldn’t happen under normal use with ingredients like bananas or frozen fruit. Your feedback is incredibly helpful, and we’ve shared it with our product team to investigate further.\nWe’d love the opportunity to make this right. Please reach out to our Customer Support team at 1-800-365-0135 with your purchase details, and we’ll do our best to assist you.\nThank you again for bringing this to our attention. We appreciate your honesty and hope to restore your confidence in Ninja.\n\nWarm regards,\nNinja Kitchen US

Stopped working after a few uses

It worked really well for a month or so, then it was a little less responsive, and now it wont even blend. I put t on the charger and it shows solid green (fully charged), I take it off the charger and after pressing the power button it shows solid purple (ready to blend)... nothing happens. I try to press it again and then it blinks from purple to red to purple to red. I have tried all the tips and tricks online and nothing has helped... I am really disappointed because I really enjoyed this item while it worked, but I ended up just wasting 60 bucks.
No, I would not recommend this to a friend.

Small but mighty, I was able to quickly make my smoothies. It definitely cuts time in half. The color I bought is perfect. I definitely recommend it.

Love it, but needs quality improvement

My partner and I both have one of these blenders and we love them for making post-workout smoothies with protein powder and frozen fruit. But, we have both experienced what other reviews mention that it stops working. Shows purple (ready to blend), then goes to red after clicking the start button and doesn’t blend. Ninja just issued me a replacement as my last one only lasted 3 months. Hoping this one lasts longer and they improve this product because it is truly so handy!
I would recommend this to a friend!

Horrible product

Ninja is a really substandard brand. I have owned this model and a big expensive blender of theirs and they both broke down very quickly. Like most companies they build in planned obsolescence and it’s a really shady way of doing business. Don’t buy Ninja.

Terrible Blender
on November 6, 2025
Posted by: 21Samual
from Arizona
Gender:Male
THE worst blender ever owned. It takes me probably 20 minutes to make a smoothie. The battery will die after two blends. I spend more time trying to get the blades to unlock than anything, you’ll do all the remedies such as shake it, add more fluids ect. The blender only blends half your smoothie. So then you shake it and then fight with the blades to unlock again. The blender works for 10 seconds then shuts off and then you fight AGAIN with the blades unlocking. Honestly biggest pain.
