Even if the cup is not full, plenty, when I am blending the water goes outside The cup is well closed.
My NutriBullet #1 lasted for four 1/2 years (4.5), with daily use !!!!! Wow!
Now, I'm enjoying my NutriBulet #2 every day, usually with apples & oranges.
I have seen other choppers online but none spin at 20.000 RPM and they
all have complicated buttons. NutriBullet is so simple. Just fill it & run it !!!!
