Consumer Reports first tested the NutriBullet Pro 900 blender in May 2014. After a blade in two separate units cracked or broke during our standard durability test, we designated the machine a Don’t Buy: Safety Risk. For this stress test we crush seven large ice cubes 45 times to simulate rigorous use. 

Our policy is to revisit products that receive such a designation, whether for safety or performance reasons, to see whether they’ve been changed in any significant way. So we recently purchased several new NutriBullet Pro 900 blenders. Upon close inspection, we thought the blades appeared thicker. Sure enough, the blades from our 2014 units were about 1 millimeter thick but the new blades measured just under 1.5 millimeter.

We ran our durability and performance tests with the new units. Following our standard protocol, two new samples were subjected to our tough durability test, and neither showed any sign of damage or stress. As a result, we're removing the Don’t Buy: Safety Risk designation from the NutriBullet Pro 900 blender. A third new sample was used for our performance testing.

We informed the company, NutriBullet, of our findings as well as the Consumer Product Safety Commission. 

If you already own a Nutribullet Pro 900, inspect the top of the blades. The ones that passed our tests are stamped with a six-character code that we think is a date code. The older blades had no such markings.    

Parsing the Performance

In our tests, the latest version of the NutriBullet Pro 900 no longer presents a safety issue. But how does it perform? It received an overall score of 53 on our 100-point scale. 

Its score was dragged down by a fair performance in our ice-crush test (a less-taxing version of our durability test), designed to see how well a blender turns ice into fluffy snow, say, for a slushy. So did its average showing in our icy drinks/smoothie test, which involves whipping up a nonalcoholic pina colada out of cream of coconut, pineapple juice, half and half, and ice.   

Both tests call for ice. Following our Don’t Buy: Safety Risk designation in 2014, Nutribullet responded by stating that the device isn't a blender or an ice crusher. The company added that crushing ice with the NutriBullet Pro 900 without adding water or another liquid was a misuse of the product.

We reached out to Nutribullet for comment on our latest findings but didn't receive a response.   

The Nutribullet website and user’s manual still refer to the device as a “nutrition extractor” designed to “break down, pulverize and emulsify foods so you can access the hidden nutrition inside.” The NutriBullet was excellent in our purée test, in which we make soup from soft vegetables. The results were smooth and consistent. It’s likely that many ice-free Nutribullet recipes for drinks, or “blasts,” as the company calls them, will turn out similarly. That includes the spinach-based “Skinny Blast” and the “Beauty Blast,” with its combination of Swiss chard, pineapple, berries, and cashews.

But the Nutribullet manual gives you the option of adding ice as long as it doesn’t make up more than 25 percent of the total ingredients. Based on our other ice-based tests, this model’s performance might not be quite as consistent if you go that route.
