Review on Commercial-Grade Vacuum Blender For Maximum Antioxidant Preservation - Tribest Dynapro DPS-1050A-B by Fred Reid

It is a super powerful blender. I have been mainly been using it for smoothies. I have yet to use it for soups and other concoctions. It is very easy to clean and and has replacement gaskets for the small top that fits on the lid. Too bad that it doesn’t have a muffler because it is extremely loud. Perhaps it lacks one for necessary airflow.The only negative thing that I have to say about it is that I hope that the vacuum pump isn’t defective because the NiCad batteries that I used in it only worked for the first charge which lasted around three days a week for a few weeks. When I had to recharge the batteries the pump stopped working. I switched to a reliable brand of rechargeable batteries (ENELOOP) but they still failed in the pump but worked in an ultraviolet flashlight. Time to try alkaline or some other non chargeable batteries, which I don’t have at the moment.Update May 13, 2021: My bad. I take back the negative comment. At first the alkaline batteries didn’t appear to work either so I called the Tribest Dynapro Commercial Vacuum Blender DPS-1050A Service Number and found out that the vacuum pump has a partially removable battery tray with EIGHT BATTERIES. The manual was not clear and di not state or illustrate this. Works beautifully now after replacing all batteries with fresh rechargeables.
