The main attraction about these new machines is the single serve blending cup. What’s unique about the Vitamix cup that no other single serve machine currently offers is that it’s double-walled insulated. This keeps your hot liquids hot and your smoothies cold for long periods of time. The inner wall protects your liquid from losing temperature, while the outer wall protects your hand from the temperature of the liquid.
The Nutribullet uses a cheap, plain cup, which is not insulated. After a short time, you end up with the “wet cup syndrome” (a liquid with ice cubes will visibly make the cup frosty).
An improvement to the Nutribullet Rx (like the Vitamix) is that it has metal gears with a drive socket and a blade base. Unfortunately, the blade base on the S30 still uses cheap plastic housing construction.
On the Vitamix, not only do the drive socket and the blade base have metal gears, but the blade base on the Nutribullet has all metal housing construction.
Both blade bases in either blender require the use of a rubber gasket to prevent liquids from leaking. These have to be removed daily for cleaning to prevent the formation of contaminants.
The gasket of the Vitamix sits on the outside of the base, but the gasket of the Nutribullet sits on the base’s inside. The Vitamix gasket is easy enough to remove and when putting it back on. On the other hand, you’ll find there’s trouble trying to remove the gasket off the Nutribullet, having to pry it out with a utensil like a butter knife. Almost as equally cumbersome is reinserting it, constantly having to stretch it to get it into a proper position, putting your fingers in harm’s way of the blades (difficult to avoid).
A universal design flaw with the Nutribullet machines?
If (and when) spillage occurs, liquid will seep down into the cooling holes where the motor is found on the Rx. Once liquid gets in and gets sticky, it’s not going to be coming out easy (if at all). The housing on the Vitamix drapes over the cooling holes, protecting them from ever interacting with liquids or spilling accidents.
There are only two settings with the Nutribullet. It’s either ‘Off’ or ‘On’.
With the Vitamix, it has a variable speed control knob (1-10). The lowest speed works really well for dressings, higher speeds for making sauces, or the top speed for making ice cream, smoothies, or nut butters.
Another feature the Nutribullet lacks is a dedicated pulse switch, something you’d use for quick chopping and to break down ingredients that are thicker.
Shortcomings of the Nutribullet Rx
While the drive socket and blade base in the Nutribullet have metal gears (reducing the chance of wear with normal use), you’ll eventually run into an operating problem. In order to stop the machine out of the pre-set time, you have to take the blender jar off the base when the unit’s still running. You don’t want to do that daily as the gears can grind down, especially if you pull the jar off at a slight angle.

Making hot soup is a new feature with the Nutribullet Rx, but the soup button is very unclear (found at the bottom). Rather than the button being labeled something like ‘Soup’ or similar, it lights up green and pressing it turns on the soup mode (the green light is now red), which blends for 7 minutes. If you accidently press it, there’s no way to turn it off. You end up having to pull the cup off when it’s still operating (a no-no as mentioned earlier).
Although advertised as a high-performance blender, the Nutribullet comes with a cheap power cord that is quite thin and generally used for a lamp, radio, or clock. Most quality kitchen appliances use a power cord of heavy duty material.
With the Vitamix S30, the thick 3-pronged power cord attached to it will have a far better shot of withstanding the test of time in your kitchen.
Eating your Soup vs Drinking it- Vitamix S30 Edges Ahead
It’s no argument that both the Vitamix S30 and the Nutribullet Rx can make hot soup, but there’s a difference between a good soup and a gourmet soup. You can’t really do well with ingredients like garbanzo beans, black beans, or corn added to the Nutribullet to make chunky soup. This is because it runs at one speed (too fast in this instance). There’s also no pulsing action. The added ingredients end up becoming over-blended as a smooth liquid.
The Nutribullet Rx traps steam to heat the soup up, since it has no vents to allow the steam to escape. The top lid might appear like it’s going to blow off due to the pressure (not safe for the user!).
Gaps are cut around the Vitamix lid plug for steam to escape. This way the soup will heat up gradually without a rise in pressure.
Nutribullet Rx- a Missed Opportunity
One feature worth highlighting you won’t find in the Nutribullet is the drainage hole built into the Vitamix S30 in case there’s a leak. This greatly protects the blender from water damage.
The production of the Nutribullet Rx takes place in China. Unfortunately, some of their electronics are being outsourced there and the parts used are cheaper to save money. So, a prospective consumer eyeballing an Rx will think they’re getting something great (a revised Nutribullet model), but they might find it breaking down faster than expected.
The Vitamix S30 is made by a family-owned company in the USA. Many of the parts in the Vitamix are hand-built.
Which blender has the better warranty?
The Vitamix. It has a full 5 year warranty including normal wear and tear. The Nutribullet Rx has a limited warranty of 1 year.
COST of a Nutribullet Rx vs Vitamix S30
Nutribullet’s use of buzz words in their advertising write-ups (like “Nature’s prescription”) and the late-night infomercials, try to take advantage of the uninformed consumer and to touch on their emotions when actually the Rx machines can’t do half of what they say it’s capable of, let alone doing them well. But, because the Nutribullet Rx is more portable and budget-friendly than an S30, some will certainly favor those qualities.
In case you’re not already familiar:
With the Nutribullet Rx, you get:
-2 single serve cups (a 30 ounce and one 45 ounce)
-1 liter super blast pitcher
-one set of blades
-one pitcher lid
-1,700 watt high torque powered base
With the Vitamix, you get: a 20 ounce single serve cup, a 40 ounce standard blending container, a set of blades, and a variable speeding control knob.
