Details important; read instructions carefully and use first time when you aren’t rushed. Of course, these details are always important when using your VitaMix anytime, so that’s kinda the same.   But it was a little hard to visualize the operation initially. But works well with no leaks and I don’t make too much at a time.   Because fresh smoothies do not taste right the next day, only the day they’re made.    
I’m a fan and recommend this product.   Yes I’d buy it again.
