My husband bought this because our 600 seemed to blend slower now. Especially since I started blending Kale with the stems on it and frozen bananas without liquid. The pro is faster and now I'm following the direction and adding water with my frozen ingredients. I like watching the YouTube videos featuring diets that consume a lot of plant based foods like FullyRawKristina. I wish I had a vitamix but since I don't this is working fine. The benefit of a vitamix is that you could adjust the food with a paddle while it is blending. With this I just pulse or stop blending, take the blender portion off and then mix the food up or add a little more liquid. I like that this is 1/6th of the cost of a vitamix so I will work with the limitations.
I received it for a Mother's Day gift and I love it. It is small enough to leave on the counter and easy to clean. Makes eating fruits and vegetables tolerable.
I bought this product about in April and has been very useful. As long as you follow the instruction, it works very well. Nice smoothie blend and a must have if you are a smoothie enthusiast. I have has a couple of times that the smoothie tried to come out in the process. Found out I backed it too full. On one or two occasions too I have had to struggle to open it due to closing it too tight or the sweat on the jar due to the frozen fruits used.
