This is actually not my first Ninja blender but our other one was getting old. What I HATED about the old the blender was how deafeningly loud it was. Unfortunately this one was also very loud! It’s the price you pay for a powerful blender. 

The blend sense technology does seem to work (see photo) however the manual says it’s also supposed to detect when you need more liquid which it did not for this test run (see video). Maybe the liquid feature only works with the larger pitcher?

If you’re looking for a powerful blender this is it. However, if you already own a Ninja i’m not sure this is worth the upgrade just for the blendsense technology.
