Walk into any thrift store or look at a "moving out" sale on Facebook Marketplace, and you'll probably see a lot of cheap, burnt-out blenders. They look sad. Their plastic gears are stripped, and their motors smell like ozone after trying to crush a single tray of ice. But you rarely see a Ninja Mega Kitchen System BL770 in that pile. It's a workhorse. Honestly, it’s one of those rare kitchen appliances that actually lives up to the "Mega" in its name without feeling like a marketing gimmick. People buy it because they want a Vitamix but don't want to drop six hundred bucks on a machine that basically just spins blades really fast.
The BL770 is loud. Like, "scare the cat and wake the neighbors" loud. But that 1500-watt motor is the reason why. It doesn't ask for permission; it just obliterates whatever you put in it. Whether you're making a green smoothie with kale that's a little too woody or trying to turn frozen strawberries into sorbet, this thing handles it.
What Most People Get Wrong About the Ninja Mega Kitchen System BL770 Blender
A lot of folks think this is just a blender with some extra cups. That’s a mistake. If you just wanted a blender, you’d buy the Professional model and save some cash. The real magic of the Ninja Mega Kitchen System BL770 blender is the 8-cup food processor bowl. It’s not just a "nice to have" accessory. It’s a legitimate replacement for a standalone food processor.
I’ve seen people try to make dough in a standard blender. It’s a disaster. The motor bogs down, the blades get stuck, and you end up digging floury sludge out of the bottom with a spatula while questioning your life choices. The BL770 comes with a dedicated dough blade. It can handle two pounds of dough in about 30 seconds. Think about that. You can go from raw ingredients to a ball of pizza dough or cookie batter faster than you can find the delivery app on your phone.
The Total Crushing Technology Reality Check
Ninja loves to talk about their "Total Crushing" blades. It's a vertical tower of blades rather than the little four-pronged star you see at the bottom of a NutriBullet or a kitchenAid. Does it work? Yeah, it’s incredible for ice. If you want snow-cone consistency for a margarita or a slushie, nothing beats this blade design. It grabs the ice from the top and the bottom simultaneously.
But there is a trade-off. Because the blades are stacked, they aren't great at creating a vortex. In a Vitamix, the shape of the jar pulls ingredients down into the blade. In the Ninja, the blades are everywhere. This means it's great for volume, but if you’re trying to make a tiny amount of pesto, the ingredients might just get flung to the sides. You have to learn how to pack the jar. Put your liquids in first, then your powders, then your greens, and finally the frozen stuff on top. This weight helps push everything into the "kill zone" of the blades.
Durability and the "Plastic" Question
I hear this a lot: "But it's all plastic!"
True. The pitchers are BPA-free Tritan plastic. They aren't glass. Some people hate that. They think glass feels more "premium." But have you ever dropped a 72-ounce glass pitcher full of 5 pounds of smoothie? It’s a crime scene. The Ninja pitchers are incredibly tough. I’ve seen these things take a tumble off a counter and survive with nothing but a scuff.

The downside of the plastic is that it can "cloud" over time if you're constantly blending abrasive things like grains or seeds. It’s cosmetic, mostly. However, you do need to be careful with the dishwasher. While Ninja says they are dishwasher safe, the high heat of some "Sanitize" cycles can eventually make the plastic brittle or cause the gaskets to leak. If you want yours to last five years instead of two, hand-wash the pitchers. It takes two minutes. Just don't touch the blades—they are genuinely surgical-grade sharp and will cut you if you even look at them wrong.
The Single-Serve Hack
One of the best parts of the Ninja Mega Kitchen System BL770 blender is the Nutri Ninja cups. You get two 16-ounce cups with "to-go" lids. This is where most people spend 90% of their time.
If you're making a post-workout protein shake, using the giant 72-ounce pitcher is overkill. It’s more cleaning for no reason. The single-serve cups use a different blade attachment that is actually better for emulsifying small amounts of liquid. It’s perfect for salad dressings, too. You can make a balsamic vinaigrette in seconds, pop the lid on, and stick it right in the fridge.
Comparing the BL770 to the Competition
Let's talk about the elephant in the room: Vitamix and Blendtec. These are the gold standards. They have metal drive sockets and 7-year warranties. The Ninja uses a reinforced plastic drive.
Is the Vitamix better? If you are a professional chef or you make hot soup by friction (yes, a Vitamix can do that), then yes. But the Ninja Mega Kitchen System BL770 blender costs about a third of the price. For the average person who just wants a smoothie that isn't chunky and the ability to chop onions without crying, the Ninja is the smarter financial move.
- Motor Power: 1500 Watts (More than most entry-level pro blenders)
- Versatility: It's 3 machines in 1 (Blender, Food Processor, Nutrient Extractor)
- Ease of Use: Four dedicated buttons. No confusing dials or "smart" screens that break.
- Safety: The lid must be locked and the handle down for it to spin. It’s basically toddler-proof.
Real World Performance: The "Nut Butter" Test
Making almond butter is the ultimate test for a blender. It's thick, it's sticky, and it generates a ton of heat. Most mid-range blenders will trigger their thermal protection shut-off within three minutes of trying to process nuts.
With the Ninja BL770, you actually want to use the food processor bowl for this, not the tall pitcher. The wider base and the lower blade height allow the oils to release more effectively. It takes some patience. You’ll think it’s not working, and then suddenly, the "meal" turns into a paste, and the paste turns into creamy butter. The 1500-watt motor stays cool enough to get the job done, though I wouldn't recommend doing three batches back-to-back without a break.
Noise and Vibration: A Necessary Evil
If you live in an apartment with paper-thin walls, you need to know what you're getting into. This machine is loud. It's not a gentle whir. It's a mechanical roar. Because the base is relatively light compared to the massive power of the motor, it can "walk" across the counter if you don't use the suction-cup feet.
Pro tip: Make sure your counter is dry and clean before you set the base down. Those suction cups are no joke. Once they grab hold, that blender isn't going anywhere. To release them, there are little levers on the side. Don't try to just yank it off the counter or you might actually damage the housing.
Maintenance and Long-Term Care
The most common point of failure on the Ninja Mega Kitchen System BL770 blender isn't actually the motor. It’s the bearing at the bottom of the blade assembly. Over time, especially if you submerge the blade base in water for long periods, the lubricant can wash out.
If you start hearing a high-pitched squealing noise, or if you see a bit of black gunk appearing at the bottom of the blade, it’s time for a replacement. Thankfully, Ninja sells these parts individually. You don't have to buy a whole new system.
- Rinse immediately. Don't let fruit sugars or dough dry on the blades.
- The "Soap Drop" Method. Fill the pitcher halfway with warm water and one drop of Dawn. Pulse for 20 seconds.
- Dry the base. Never let water sit in the area where the pitcher meets the motor.
- Check the gaskets. Every few months, use a dull butter knife to gently pop the rubber O-ring out of the lids and clean under it. You’d be surprised what grows there if you ignore it.
Is it Worth the Counter Space?
The footprint is significant. The base is wide. If you have a tiny galley kitchen, this might be your "everything" appliance, meaning you'll have to get rid of your separate mixer or food processor to make room.
But that's kind of the point. The BL770 is designed to be the "Mega" system. It replaces a bunch of smaller, weaker tools. If you use it three times a week, it earns its spot. If you just want to make a protein shake once a month, it's probably overkill.
Actionable Steps for New Owners
If you've just unboxed your Ninja or you're about to hit "buy," here is how to get the most out of it immediately.
First, ignore the "Auto-IQ" stuff if you have a different model, but on the BL770, focus on the "Pulse" button for chopping. If you just hold the button down for onions, you’ll end up with onion juice. Two or three quick pulses give you a perfect dice.

Second, when making smoothies, use the single-serve cups for anything with seeds (like raspberries or chia). The blade design in the small cups is tighter and does a better job of pulverizing those tiny bits than the large "Total Crushing" tower.
Third, use the dough blade for more than just bread. It’s incredible for mixing meatloaf or turkey burger ingredients without overworking the meat and making it tough.
The Ninja Mega Kitchen System BL770 blender remains a powerhouse because it doesn't try to be fancy. It’s raw power and practical attachments. It’s built for people who actually cook and need a tool that can keep up with a busy Sunday meal prep session without dying. Respect the blades, clean the gaskets, and don't be afraid to use the food processor bowl for things other than dip—it's the unsung hero of the whole set.
