Battery is terrible
on November 6, 2025
Posted by: Sammmmmm
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.
No, I would not recommend this to a friend.

I cannot understand why this is not rated 5 stars. I use this everyday to make my morning smoothie. I sits on the counter ready to use. Easy clean up and easy to use. I love my blast !!!

Won't last more than 6 month if used daily.
on November 12, 2025
Posted by: m4l490n
I bought two of these the last 6 to 8 months and they are broken already. Please beware that if you are serious about your shakes and make multiple each day, this blender will not last more than about 6 months. It is only meant to be used casually once every other day or so.

Worst purchase ever
on November 21, 2025
Posted by: Unhappy1234567
from New Hampshire
The battery does not last through one single use. I have to begin blending, stop to let it charge, and then finish. The blades are so small they did not even properly blend a simple smoothie. Seriously, do not waste your money on this terrible product. I think I’m going to be just throwing it away. What a waste.
No, I would not recommend this to a friend.

Horrible Product
on November 30, 2025
Posted by: Sultan A
Gender:Male
Horrible product. Please do not buy this product. It stopped working and I reached out to the support desk. They told me it is not under warranty without even looking at the product or offering trouble shooting to fix. All they offered was a 30% discount on the next purchase. Extremely bad product and support service. Stay away from any Shark or Ninja products.
No, I would not recommend this to a friend.
