You need a good blender. You want speed. You hate to waste cash. I put the Ninja Bl660 Vs Bn751 to the test. I used both tools in my own home. They both make a great protein shake. They crush ice fast. Read on to see which ice crushing blender wins for you.
Ninja BL660 Review
This is an old, high speed blender. It gives you raw power. It has basic buttons. I love how simple it is to use.
Pros and Cons
It wowed me with pure speed. It lacks smart traits.
| Pros | Cons |
| Strong 1100-watt motor | Very loud noise |
| Good pulse setting | No smart keys |
| Two 16 oz cups | Cups feel small |
Real Experience After Months of Use
I used this blender each day. It helped my morning rush. The smoothie texture is very nice. It eats frozen fruit right up. The sharp blades are great for crushing ice. Thick blends are hard, though. It is not a good nut butter blender. The wide blender jar makes you scrape the sides a lot.
The loud motor will shock you. It will wake the house up. The lid fits tight. I feel relief that it does not spill. Pouring is a breeze. The base fits well on the counter. Cleanup is fast if you rinse right away.
Recommendation
This is perfect for budget buyers. Get it if you just want raw power. Skip it if you want smart buttons.
Ninja BN751 Review
This model is a big step up. It has smart keys that do the work. It looks sleek and clean on the counter.
Pros and Cons
I loved the hands-free use. I did not like the tall base.
| Pros | Cons |
| Smart Auto-iQ keys | Tall to store |
| 1400 peak watts | Still very loud |
| Big 24 oz cups | Costs more |
Real Experience After Months of Use
This personal blender setup is a joy. The smart keys stop and start the motor for you. My post-workout drink is perfect each time. It pulls down hard chunks with ease. It leaves no bits behind. The big cups hold lots of food. I skip the main jar most days.
It shakes the counter on high speed. It is just as loud as the old one. The tall blade needs care to wash. But the thick shake it makes is so worth it. It feels strong. It holds up well to daily use.
Recommendation
This is perfect for busy folks. Get it if you want a top smoothie blender. Skip it if you want to save cash.
