Most and Least Reliable Blender Brands

We ask our members about the products they own, and we use that data to make projections about how new models from a given brand will hold up over time. In a previous survey, CR members told us that they expect to use their blenders for about eight years, and 92 percent of all blenders purchased between 2013 and 2021 were still in use.

Our reliability survey doesn’t distinguish between specific models but rather by brand. You can find information on predicted reliability and owner satisfaction, as well as model-specific information, in our blender ratings.

“The ones rated toward the top for predicted reliability, with the green-colored ratings, are more likely to operate as expected in the long run,” says Nick Gallivan, a CR survey research associate. “The ones rated toward the bottom, with the orange ratings, are more likely to give owners a problem-filled experience.”

We also ask members how likely they are to recommend their blender, and that serves as the basis for our owner satisfaction ratings.

Based on our surveys, the blender brands that CR members are most likely to own are Ninja, Vitamix, and NutriBullet. Ninja accounted for 44 percent of all blenders purchased in 2023. Vitamix, its closest competitor, has a stellar reputation for performance and power (it claims four of the top five positions in our blender ratings), but its models are pricier. For personal blenders, Ninja had a 45 percent market share and NutriBullet had 34 percent.

But are these favored brands the best investment? Below are the best and worst brands for full-sized blenders and personal blenders in terms of reliability and satisfaction.
