Ten years for the bearing to wear out with moderate use. Actually was able to get bearings and rebuild the old one but caught a good sale so I went ahead and bought a new one. You can't go wrong with a vitamix.
I have had my Vitamix TurboBlend 4500 for many years and we use it daily. When I wore out my 2nd container and needed to buy a 3rd, I was so pleased to find the Classic 64-ounce Container was still available. It works beautifully with my old TurboBlend.
I purchased a new blender jar after the original (new 12 yrs ago) malfunctioned. I’m able to whip up delicious smoothies & shakes, salad dressings, and soups again!
Pros: Speed of Service, Texture Quality, Durability, Power
Difficult to keep clean, would prefer glass or stainless steel.
Pros: Power

Hi there! The container can sometimes form a film or cloudiness from the minerals in the healthy fruits and vegetables we blend in our Vitamix. When this occurs, we recommend pouring equal parts of water and white vinegar into the container. Let the container soak in an upright, standing position for several hours, then pour the contents out and use a soft pot scrubber to clean the inside of the container. Please be cautious when cleaning around the blade assembly. Also, please keep in mind that it may take several attempts before the staining/discoloration is completely removed. We do offer a Stainless Steel Container also, it can be found here: https://www.vitamix.com/us/en_us/shop/48-ounce-stainless-steel-container
I bought the original Vitamix machine at least three decades ago, and it's always run great, granted my containers I have wore out hahaha. Now that I have the new container I feel like it's invincible. Vitamix you're the best
