Terrible Blender
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.

It started out great but now even after charging it for hours I go to use it once and three seconds later it shuts off and flashes red.

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.

Newly purchased, packed blender in my carry on bag. TSA confiscated the blender at the airport security screening. Wish the product marketing had a warning that the blender is not TSA compliant. Or perhaps package the blender with sheaths on the blades and that might make the blender TSA approved.

Hi there, Thank you for sharing your experience with the Ninja Blast. We’re so sorry to hear about the inconvenience you faced during your travels, we understand how frustrating it must have been to have your new blender confiscated. While the Ninja Blast is designed to be portable and travel-friendly, TSA regulations regarding bladed items can vary by airport and security personnel. We appreciate your suggestion about including a TSA compliance warning and protective blade sheaths, that’s incredibly valuable feedback, and we’ll be sure to share it with our product development team. Thank you again for your feedback, it helps us improve and better serve our customers. Warm regards, Ninja Kitchen US

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).

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.

Junk
We bought this about 6 months ago. We returned it 4 times and now we are returning it again for the fifth time, and will buy a different brand. The motor keeps dying after a few weeks. All we use it for is to make smoothies. We have an older ninja machine that works great. This thing is nothing but junk. I don't understand why people have positive reviews on this thing...
