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 test 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.

Every year we ask our members about the products they own and 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.”

More on Blenders

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 on nearly 60,000 blenders purchased by CR members between 2012 and 2020. You can find information on predicted reliability and owner satisfaction in our blender ratings.

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, Hamilton Beach, KitchenAid, Ninja, Oster, and Vitamix.

Most Reliable Full-Sized Blenders

CR members have told us that they expect to use their blenders for about eight years. But judging by our brand reliability ratings, that might be optimistic.

Most brands receive only a moderate rating of Good for predicted reliability. And only a handful receive a rating higher than Good for owner satisfaction. In fact, Vitamix and Wolf are the only blender brands to receive top ratings for both predicted reliability and owner satisfaction. Ninja isn’t far behind, receiving Very Good ratings for both predicted reliability and owner satisfaction. And Oster gets a Very Good rating for reliability and a Good for satisfaction.

CR members with digital access can take a closer look at two full-sized blenders from brands that earn 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 gets a subpar rating of Fair for reliability.

The rest of the brands—Black+Decker, Breville, Braun, Cuisinart, Dash, Hamilton Beach, KitchenAid, and NutriBullet—receive a middle-of-the-road rating of Good for predicted reliability.

Most Reliable Personal Blenders

Braun and Breville are the only personal blender brands in our survey to earn top marks for reliability. Ninja comes close. Braun and Ninja also earn Very Good scores for owner satisfaction.

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 earns a Fair rating for reliability (the second lowest possible rating) and receives a middling rating of Good for owner satisfaction. Bella’s ratings are just as unimpressive.

Cuisinart, Hamilton Beach, and Oster do slightly better, netting Good ratings for both reliability and satisfaction. Black+Decker also gets a Good rating for reliability, but it’s the only brand to get our lowest rating for owner satisfaction, meaning our members aren’t very likely to recommend Black+Decker 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.
