Most and Least Reliable Blender Brands
CR's exclusive member survey reveals the blenders that last
If you choose a new blender solely on price or design, your experience—whether you’re using it for smoothies, soups, or meal prep—could be crushed like ice.
What’s more important, long term? A blender’s performance, and its brand reliability. The latter can also influence when you’ll be shopping for your next blender—sooner, in some cases, or later.
So you want a powerful blender that’ll last. Our engineers conduct exhaustive tests on blenders—evaluating their ability to crush ice, make smoothies, and purée soups—to help you choose one that deserves to grace your countertop. And we factor in predicted brand reliability and owner satisfaction ratings, based on data from our annual member survey.
Most Reliable Full-Sized Blenders
CR members have told us that they expect to use their blenders for about eight years. In fact, 92 percent of all blenders purchased between 2013 and 2021 were still in use.
Most brands received only a moderate rating of Good for predicted reliability. And only a handful received a rating higher than Good for owner satisfaction. Vitamix and Wolf were the only full-sized blender brands to receive top ratings for both predicted reliability and owner satisfaction. Calphalon also received an Excellent score for predicted reliability and Good rating for owner satisfaction. Ninja wasn’t far behind, receiving Very Good ratings for both predicted reliability and owner satisfaction. Oster and Hamilton Beach both earned a Very Good rating for reliability, but respectively, only got Good and Fair owner satisfaction scores, respectively.
CR members with digital access can take a closer look at two full-sized blenders from brands that earned an Excellent rating for predicted reliability and perform well in CR’s lab tests.
Least Reliable Full-Sized Blenders
At the other end of the spectrum, Blendtec and Braun got a subpar rating of Fair for reliability, so we cannot recommend them at this time.
The rest of the brands—Black+Decker, Breville, Cuisinart, Dash, KitchenAid, and NutriBullet—received a middle-of-the-road rating of Good for predicted reliability.
Most Reliable Personal Blenders
Braun and Breville were the only personal blender brands in our survey to earn top marks for reliability. Ninja and Vitamix came close. Vitamix earned Excellent scores for owner satisfaction while Ninja got a Very Good score.
CR members can read the personal blender ratings and reviews of two high-performing picks from Breville and Ninja below.
Least Reliable Personal Blenders
Despite its name being almost synonymous with personal blenders, NutriBullet earned a Fair rating for reliability (the second lowest possible rating) and received a middling rating of Good for owner satisfaction. Bella’s ratings are just as unimpressive.
Calphalon, Cuisinart, Hamilton Beach, and Oster did slightly better, netting Good ratings for both reliability and satisfaction. Black+Decker also got a Good rating for reliability, but its subpar owner satisfaction rating (Fair) means our members aren’t very likely to recommend this brand’s personal blenders.
