The ultimate Nutribullet RX review – warts and all!

Here at A Juicy Blend we’ve been eager to put our Nutribullet RX review to the test, to complete our series looking at the different Nutribullet machines on sale in the UK.

So if you’re interested in a powerful blender with a heating element for soup, read on – or if you’ve made up your mind already you can buy the RX from Amazon, John Lewis or Currys. There is not much to separate them on price, but if you’re looking for a bargain, check out our prices page for the latest deals. The RX is currently retailing for around £169.99.


What is the Nutribullet RX and how much does it cost?

This hefty price-tag of £169.99 makes the Nutribullet RX about £80 more than the Nutribullet Pro 900 series, and nearly £115 more than the Nutribullet 600 series (again, at the time of writing), so what do you get for your money?

We take a look at the new design and functionality that comes with this handy and powerful little kitchen gadget, and also address some of the reliability issues that have been reported.

Nutribullet RX vs Nutribullet Pro and the rest

Like the Nutribullet 600 and the Nutribullet Pro 900, and even the Magic Bullet before it, the principle of the Nutribullet RX remains the same.

Contrary to what some people think, it is not a juicer and shouldn’t be considered as one. It is a high-intensity blender that extracts nutrients from the food that you put into it – Nutribullet calls its devices ‘extractors’ rather than blenders because of their ability to handle even skin and pulp, nuts and seeds without a second’s hesitation.

The special ‘cyclonic action’ is the key to how the machines work, which is why it’s important not to overfill them or the blades can become jammed.

Nutribullet RX vs Nutribullet Pro 900

If you’re trying to decide whether to buy a Nutribullet RX or a Nutribullet Pro 900, then please consider this quick table summarising the key differences between the machines.

Nutribullet Pro 900

  • Power: 900 watts
  • Weight: 2.5kg
  • Dimensions: 13 x 13 x 36.5 cm
  • Warranty: 1 year
  • Colour: Champagne
  • Functionality: Blender only
Buy from Amazon

The Nutribullet RX is 1700 watts of pure power

The Nutribullet RX is the most powerful blender of the series, packing a powerful 1700 watts and 2.3 horsepower motor that simply dwarfs the 600 and 900 series. This promises to create a much smoother consistency than the weaker motors. However with greater power comes greater noise – and if you’re going to be making soup in it, as we discuss in a bit further on – then you’ll need to put up with it for seven minutes!

Nutribullet RX accessories

Everything is bigger and better with the Nutribullet RX – so whilst the Nutribullet 900 Pro impressed with its Colossus cup that holds nearly a litre, this pales into insignificance compared to the RX accessories. Clearly intended for families or batch preparation, it comes with a Short cup of 352ml as well as a Large cup and a Pitcher of 1278ml each.

It’s worth noting that the cups are not interchangeable between the smaller models and the RX, so if you already have a 600 or 900 series, you won’t be able to use the accessories on this latest machine.

As with all the Nutribullet cups, those that come with the RX are top rack dishwasher safe and BPA free.

In terms of blades, the RX is less generously furnished that the earlier models, and only comes with one extractor blade. This is accompanied by a blade remover, and it is very much recommended that this is used for removing the blade for washing, otherwise there is a risk that the gasket may come loose – more of this later. The blade should always be washed by hand, not in the dishwasher.

Finally there is one lip comfort ring and one stay fresh lid – again somewhat on the light side considering the price point and the fact that earlier versions can’t be swapped in.

What the Nutribullet RX comes with

The Nutribullet RX ships in the UK as a 10 piece set that includes the following:
1 x High Torque Power Base.
1 x Extractor Blade.
1 x Short Cup (352ml).
1 x Handled Oversized Cup (1278ml) with Pitcher Lid.
1 x 1L SouperBlast Pitcher with Lid.
1 x Stay Fresh Lid.
1 x Comfort Lip Ring.
1 x Blade Remover
1 x User Manual with Recipes.
1 x BONUS Natures Prescription Hardback Recipe Book.

Nutribullet RX soup maker

A significant new feature of the Nutribullet RX is the addition of a heating element that enables you to make soup in the blender itself. This was apparently a feature that was being requested, and certainly here at A Juicy Blend we have seen a lot of interest in Nutribullet soup recipes, so it makes sense that this feature would be added.

This ability to handle heat is a big distinction from the other Nutribullets where you have to allow pre-cooked ingredients to cool before you blend them and then reheat them to turn them into soup.

The way it works with the Nutribullet RX is that you add your ingredients to the blender, for example vegetables with a broth or stock for liquid. Then as you start to blend, you press down the G-button on the front of the power base for two seconds to activate the SouperBlast Mode. You know this is working because the G-button glows starts to glow red.

This kicks off a seven minute heating cycle that will turn your blend into a piping hot and hearty soup.

It is worth noting though, that this heating cycle doesn’t actually ‘cook’ vegetables. In some instances, for example like the tomato soup used in the commercial, this doesn’t matter because the vegetables are fine just being heated. In other cases, for example with broccoli or carrots, you will need to steam the vegetables first to soften them.

Another thing to note is that a common complaint is that the soup pitcher can overflow, perhaps because people are not respecting the max line. Be conservative with your helpings, although this can mean that the portion size is a bit on the light side for two people.

You should also be careful about reading the manual’s instructions about how many times you can run the cycle before the blender needs to cool. Generally make sure you take all the precautions that Nutribullet advises when using the RX soup maker.

Watch how to make tomato soup using the Nutribullet RX

This video shows you how to make a delicious and hearty tomato soup (or souperblast) using the Nutribullet RX.


  1. 4 large tomatoes
  2. Almond milk to the max line
  3. Cashews
  4. Garlic
  5. Chia seeds
  6. Basil
  7. Salt
  8. Pepper


  • Put all the ingredients into the soup making pitcher
  • Press the ‘G’ button until it glows red
  • Wait for 7 minutes whilst the soup making cycle runs
  • Once it’s finished, remove the pitcher from the blender
  • Pour the soup and enjoy


Nutribullet RX blending functionality

Nutribullet has equipped the RX with so-called SMART Technology which means that there is even less for the user to do than before – which let’s face it, wasn’t that much in the first place!

Where with the Nutribullet 600 or 900 series, you make a nutriblast by screwing the blade onto the cup, and then placing it onto the base, sliding and twisting into the little grooves to activate the motor, now all you have to do is place it onto the motor and it will start.

There’s no more need to make a judgment call as to whether or not the blend has been properly created, now there is hands-free technology to do the job for you. The machine will turn onto exactly the right RPM for the mixture you’ve placed in it, will stop at the right intervals and for the correct amount of time. It will, so Nutribullet claim, do the thinking for you!

Now whilst some people might find this reassuring, others will find the loss of control a bit disconcerting. Also as we just mentioned, it wasn’t exactly arduous before, so we’re not sure how significant a benefit this feature is. Effectively it comes down to personal taste.

Nutribullet RX gasket problems

One thing’s for sure, you can’t do a lot of digging around about the Nutribullet RX without hearing about the gasket problems to some extent or another.

The gasket is the small rubber ring that lives in the blade housing. In all Nutribullets it is a common complaint that this ring can come loose or come off altogether, and get blended up. This has happened to us at A Juicy Blend but only when we mistakenly put the blade in the dishwasher, which is probably fair enough.

However this complaint seems particularly common in reviews of the RX judging by the outpourings on (note, there are not many reviews from the UK as it’s not so widely available over here). There are a great many comments about this coming loose and nightmare stories about it ending up in peoples’ smoothies, which is certainly not what you want.

A ‘blade remover’ is provided with the blender, but the advice on what to use it for is not particularly helpful. There are only three references to it in the manual, one to list it, and twice to say ‘hand tighten or use the blade remover to tighten the blade to prevent leakage.’There are comments from people who say that they always use the blade remover and have not had gasket issues, but then other people say they have used it without fail and the gasket has still come loose. It is certainly something to be aware of.

We have also noted reports that say that as of 2015 a new design has been released with a fixed gasket. It would appear that the gasket problem might therefore have been resolved, but we have not been able to confirm this at the time of writing.

This Nutribullet RX video shows a smoothie being made using a brand new machine, and demonstrates the new ‘no hands’ blending functionality that we mentioned above.

So is it worth buying the Nutribullet RX?

Here at A Juicy Blend we have been impressed by the specification and functionality of the Nutribullet RX. It addresses one of the few issues we have with the 600 series in that the size of the cups is now ample. We also really like the soup functionality and the 1700w motor undoubtedly creates an exceptionally smooth blend.

However the gasket issue is something that concerns us and unless the reports of the newer design with the fixed gasket are correct,  there doesn’t seem to be a way around it other than to use the blade remover to tighten the blade each time and hope for the best.  Alternatively you could try not to remove the blade from the cup and wash the two together. This is obviously not ideal and detracts from the practicality of the one-cup functionality.

We recommend that if you decide to take the plunge and make a purchase, that you ensure that you are buying from a registered stockist of the Nutribullet RX here in the UK. That way if you do have any issues then you’ll be able to get an exchange or refund with no quibbles provided the machine is still under its 1 year warranty.

We really hope that this Nutribullet RX review has helped you in your buying decision. If you are still considering your options then why not check out our Nutribullet 600 vs 900 review, or our Nutribullet vs Nutri Ninja comparison.
