Review on Commercial Vacuum Blender With Anti-Oxidation - Tribest DPS-1050 Dynapro, Gray by Cordany Grissom

I was hoping this would fix my major complaint with Vitamix 6300 - I don't like froth/bubbles in my smoothie. I use my much cheaper nutri ninja auto IQ when not adding tough ingredients - it does not create froth or bubbles as works better than Vitamix then. Finally I can replace those two blenders with one was my thought.I was excited to see the air bubbling out of the water and going up when using the pump. But when the smoothie was done, it actually had more froth than the Vitamix. With my tall jar, I usually pulse the Vitamix on and off and get rid of most of the bubbles and froth. Same trick did not work with this blender. Was I doing something wrong ? But I did feel the air rush in when opening the flappy thing in the lid, so the pump created some vacuum. Tried the next smoothe with 60 seconds of pumping instead of the suggested 30 seconds. Again the problem with bubbles and froth.I was determined to make this work, mulled it over for a couple of days and tried again. No luck. Thanks to amazon prime, returning this.
