The program settings work perfectly (for smoothies / frozen desserts / hot soups), as do the toggle switches. Just load the container with your smoothie ingredients, switch to the program, switch the toggle on and walk away. It speeds up slowly, and shuts off automatically after a certain time. When using it manually, the variable speed setting occasionally acts up, so at some point a new speed control dial may be necessary – not sure – maybe it just needs a start / stop switch Container is good as are the blades See this link for more info https://www.blendguide.com/vitamix/vitamix-6300 New cost is over $600 CDN plus tax Asking $150 If you email me your contact info, I will try to get back to you ASAP
