How we test the NutriBullet and other single-serve blenders


Here's how we test the NutriBullet and other single-serve blenders to find the models that give you the best results.

Putting single-serve blenders to the test


The NutriBullet is the household name in the single-serve blender category and has sparked a continuing wave of new competitors on the market. Single-serve blenders are convenient, compact and allow you to create a healthy snack on the run. Many make some wild health claims while others simply market themselves as a personal blender.

Our home economist Fiona Mair first tested these as one-off tests, but with so many more models on the market we've now put them through their first comparative test in the CHOICE kitchen lab.

Our expert testers

With 30 years of experience, our home economist Fiona has seen lots of new technology enter the kitchen space. She's a wiz in the kitchen and knows how to put any appliance through its paces to see if it's worth a spot in your kitchen.

How we choose what we test

With a range of products on the market, what makes us choose one single-serve blender to test over another? As with most of our product testing, our aim is to test the most popular models on the market and what you're most likely to see in the retailers.

We survey manufacturers to find out about their range of models, we check market sales information and we also check for any member requests to test specific models. From this information we put together a final list that goes to our buyers. They then head out to the retailers and purchase each product, just as a normal consumer would. We do this so we can be sure they're the same as any consumer would find them and not 'tweaked' in any way.

How we test

Performance

Fiona puts single-serve blenders through their paces by conducting four main tests:

  • Green smoothie She processes a green smoothie consisting of 30g cucumber, 35g celery, 35g kiwifruit, 75g pear, 75g spinach, 1½ mint leaves and 125mL distilled water. She looks for a smooth, thin consistency that's not aerated and with kiwifruit seeds finely blended.
  • Kale She processes kale to assess the blender's ability to process this tough, green leafy vegetable.
  • Soft smoothie Including frozen fruit and yoghurt, Fiona assesses the blenders' ability to create a smooth consistency with all ingredients mixed well and not aerated.
  • Ice Fiona assesses how well each blender can crush ice to an even consistency.

Extra tests are conducted (processing nuts, parmesan cheese, coffee and mayonnaise) in the blenders that claim they can be used for these tasks. These extra tests are not included in the performance score.

Ease of use

Fiona checks how small food needs to be cut to fit into the cup/bottle, ease of pouring and drinking from the single serve cup and ease of travelling with the cup. She also assesses how easy the single-serve blender is to assemble and disassemble, how easy the controls are to use and how easy it is to clean the unit.

Nutritional analysis

NutriBullet and other single-serve blenders make some pretty big claims about nutrient extraction. We send samples of green smoothie to a lab to be analysed for calcium, iron and magnesium. Because vitamin C begins to oxidise as soon as it's extracted, we measure vitamin C immediately after processing in the CHOICE labs. We give nutritional yield a low weighting in our scoring system as health benefits are unknown.
