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.

More on Blenders

Every year 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. “The ones rated Excellent for predicted reliability are less likely to have any issues in the long run,” says Simon Slater, CR’s associate director of survey research. “The ones rated Poor 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 rating. Our experts analyzed data from almost 59,000 blenders purchased by 53,408 CR members between 2013 and 2021. You can find information on predicted reliability and owner satisfaction in our blender ratings.

The top blender brands CR members are most likely to consider are Ninja, Vitamix, and Cuisinart. Over 80 percent of current Vitamix and Breville owners are likely to buy the same brand again. NutriBullet is an especially popular brand among those planning to buy a personal blender.

Below are the best and worst brands for full-sized blenders and personal blenders in terms of reliability and satisfaction. Our survey results cover 14 brands, including Blendtec, Cuisinart, Hamilton Beach, KitchenAid, Ninja, Nutribullet, Oster, Vitamix, and Wolf.

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.

As a kid in Delaware, I lived a few blocks from Bob Marley, who once said, "It is better to live on the house top than to live in a house full of confusion." At CR, I'm psyched to help readers navigate this cluttered, hyper-commercialized world we live in. I've covered luxury real estate, interior design, and culture—reporting on everything from smart home technology to racial hypocrisy at Thomas Jefferson's Monticello estate. Since the pandemic started, I cherish simplicity, covering accessible topics like decorating, cooking, and cleaning. Give me a smoothie blender over a mansion any day. Blenders are slightly easier to clean.
