I have not tried this for chopping vegetables. Manufacturer feature states that it is having all the power you need to mix, puree, dice, crush ice, and more. In my experience, these type of blade design is generally ideal for fluid and semi-solid blending/grinding. Wave Action system pulls mixtures down into the stainless steel blades for incredibly smooth results. And, that's the reason I am able to make great smoothies on this blender.
I would like to help you, fellow-buyer, but I'm sorry, I can't. The 'blender' arrived in Australia without any accessories for my use, and without an electric fitting for its use here. I have wasted $70 for an object which sits at the back of a cupboard shelf and is useless. Amazon has been told of this. Some weeks later I still await any apologetic or useful reply from Amazon.
