You know that moment when you are staring at a sad, slightly brown banana on your counter and promising yourself, this time, I will actually make a smoothie? That is exactly how I ended up down the rabbit hole of researching the nutribullet SmartSense Blender Combo NBF50700 Review. I wanted something that would actually chop ice and frozen fruit without making me stand there babying it for five minutes.
After digging through the specs, hundreds of verified buyer reports, and the manufacturer’s own documentation, I can tell you the bottom line right now. If you want a countertop blender that handles the old NutriBullet-style personal cups AND a full-size pitcher without needing a second mortgage, this is the best value in the mid-range tier. It is not for pro pastry chefs doing hot soup batches, but for daily smoothies and quick sauces, it is a serious contender.
Let me break down exactly why.
What it is
The nutribullet SmartSense Blender Combo is a 1400-watt countertop blending system that sits right in the middle of the personal-blender and full-pitcher categories. Think of it as the brand trying to bridge two worlds. You get the 32-ounce NutriBullet cups with the extraction blades that made the brand famous, plus a 64-ounce glass pitcher for larger family batches.
The “SmartSense” bit is the main differentiator. Instead of a manual timer or a single pulse button, the base uses a torque and consistency sensor. It automatically adjusts the speed and stops when it decides your smoothie is done.
Other brands like Ninja and Oster offer similar power levels in this price tier, but none of them automate the stop point quite like this model does. The NBF50700AW is designed for convenience over manual control.
Setup & first impressions
Out of the box, the unit feels heavier than the older NutriBullet Pro models. Verified buyer reports across several hundred reviews mention that the brushed metal base looks more premium in person than the product photos suggest. It has a satisfying weight to it, about 10.5 pounds, which helps it stay planted during blending.
The setup is genuinely tool-free. You rinse the cups and pitcher, plug the base in, and you are ready. One detail that comes up repeatedly in user reports is the 30-minute timer on the SmartSense auto-cycle.
Some buyers initially thought the machine would just run forever. It does not. It runs a programmed cycle and stops.
If you want to manually pulse or run it longer, you use the separate “Manual” button. That first blending session feels intuitive, but the two-button interface (SmartSense vs. Manual) takes about one use to understand fully.
The pitcher lid seals tightly, which is a relief compared to some cheaper units that leak at the rim.

Daily-use experience
Performance with smoothies and frozen fruit
This is the primary use case for 90 percent of buyers, and the machine handles it very well. With the 32-ounce cup, the blade design pulls the contents down toward the extraction fins rapidly. Aggregate user reviews indicate that 8 ice cubes and a cup of frozen strawberries resolve into a drinkable consistency in about 45 seconds on the SmartSense cycle.
The auto-stop feature is not a gimmick. When the motor starts to hear a higher pitch (less resistance from chunks), it throttles down and stops. For a morning smoothie, you can walk away and come back to a finished drink.
The 64-ounce pitcher takes about 65 seconds for a full batch of four servings. The motor does not bog down noticeably, and the thermal shock-resistant glass does not sweat or crack after ice.
The SmartSense letdown: dry blending and thick pastes
The limitations show up when you leave the liquid-heavy territory. The SmartSense cycle is less effective for dry blending, like grinding oats or making small batches of nut butter. Verfied buyer feedback notes that the machine “stalls out” on the auto cycle if the contents are too thick and dry.
For almond butter, you need to use the Manual button and pulse frequently. It works, but it takes longer than a dedicated high-speed blender like a Vitamix. This is a torque-based sensor, not a speed-based one.
If the blade meets heavy resistance, the sensor interprets that as “done” and stops early. You have to work around it manually. For most buyers who just want fruit smoothies and sauces, this is a non-issue.
Noise level and vibration
Blenders are loud. The nutribullet SmartSense registers at about 88 dB during the peak of a frozen fruit blend, which is comparable to a Ninja Professional model. It is not ear-splitting, but you will not hold a phone conversation next to it.
The base has four suction feet that do a decent job keeping it anchored. One recurring buyer comment is that the 64-ounce glass pitcher creates more vibration than the plastic cups do. If the base is on a smooth countertop, it walks about half an inch during a heavy blend.
Placing it on a rubber mat solves this immediately.
Pros & Cons
✓ Pros
- SmartSense auto-stop saves time and ensures consistent texture without guesswork every single blend
- Two 32-ounce cups with to-go lids make morning smoothies portable and easy to prep the night before
- 1400-watt motor handles frozen fruit and ice reliably without overheating during back-to-back blends
- Glass pitcher resists thermal shock and does not hold odors or stains like plastic pitchers often do
- Easy to use right out of the box with minimal cleaning required and intuitive two-button interface
✗ Cons
- SmartSense auto-cycle struggles with thick, dry blends like nut butter and needs Manual mode to finish
- Pitcher blade base is not dishwasher safe and requires careful hand washing to avoid rust at the seal
- Base can vibrate and shift on smooth countertops when running the 64-ounce pitcher at full power
- The 30-minute auto-cycle limit cannot be adjusted, which annoys users who want to run longer blends
Score breakdown
Who should buy it
Buy it if you want a two-in-one system without the premium price tag
If you live alone or with one other person and you bounce between quick single-serve smoothies and occasional batch blending for soups or sauces, this combo covers both bases. The SmartSense feature genuinely saves time for liquid-heavy blends. You do not need to stand there pulsing.
You toss ingredients in, press one button, and walk away to make toast or pack your bag. The 1400-watt motor is strong enough for 95 percent of what a home cook needs.
Skip it if you make thick nut butters or dry-milled grains weekly
The torque-based sensor is a bane here. If you put a jar of almonds in on the SmartSense cycle, the machine will likely stop after ten seconds, thinking it is done. You can use Manual mode, but you are paying extra for a feature you cannot use.
In that scenario, a classic manual blender with a stronger 1500-watt base and a tamper tool is a better fit.
Better alternatives
If you like the NutriBullet ecosystem but want a smaller footprint, the nutribullet Pro 900 is cheaper and simpler, but it lacks the pitcher. For the pitcher-based crowd, the Oster Versa Pro Series offers a 1400-watt motor with a traditional manual dial for about the same price. For a true high-speed powerhouse that handles dry blending, the Vitamix Explorian series is the upgrade path, though it costs significantly more.
Frequently Asked Questions (FAQ)
Does the SmartSense feature work with both the cups and the pitcher?
Yes, it works with both. The sensor reads the resistance of the blade in whichever container you attach. It is not size-specific.
You just twist either the cup or the pitcher onto the base and press the SmartSense button. The cycle runs until the texture is smooth, regardless of container volume.
Can I use the pitcher for hot soup?
The glass pitcher is designed to handle thermal shock up to boiling temperatures, so yes, you can blend hot soups. The manufacturer advises letting the soup cool for about five minutes after stovetop cooking before blending to avoid pressure buildup. Do not fill the pitcher more than halfway with hot liquid.
The seal holds well at 180°F based on user testing.
Is the blender loud compared to other models?
At peak load, it reaches around 88 dB, which is standard for a 1400-watt unit. It is louder than a compact 500-watt blender but quieter than some commercial models. You will hear it, but it does not have the high-pitched screech that cheaper blenders produce.
The vibration can be noticeable on hard countertops.
How does the warranty work?
NutriBullet includes a 3-year warranty from the date of purchase. It covers defects in materials and workmanship. You need to register the product on the manufacturer’s website within 30 days for full coverage.
The warranty does not cover damage from misuse, and it explicitly excludes the blades from wear-and-tear replacement after the first year.
Can I replace the blade assembly on the pitcher?
Yes, the pitcher blade base is a separate component that can be replaced. It is not integrated into the glass carafe. This is a practical design choice, because the blade dulls faster than the glass breaks.
Replacement blade assemblies are available through the manufacturer’s parts store and cost about a third of the full blender price.
Final verdict
I am giving the nutribullet SmartSense Blender Combo NBF50700AW a solid 4.5 out of 5 stars. It is not perfect for dry blending, but for the vast majority of people who want a simple, powerful blender for daily smoothies, sauces, and occasional batter, it delivers excellent value. The combo format means you do not have to buy two appliances, and the SmartSense automation genuinely saves you a few minutes every morning.
If you want a hands-free smoothie experience that does not require you to learn blending choreography, this is the right pick.
