Question: Is this with the 64 oz. Container or 90 oz?
Document: It is marked on one side to 4 cups / 32 oz, and on the adjoining side to 1000 ml. The container is narrower at the bottom and widens significantly at the top.--- "WildSide", which is 5-sided with a 4" blade. It is marked on one side to 36 oz, and on the adjoining side to 1000 ml, but these markings go only to about the halfway point on the container side and it will clearly hold significantly more volume than the FourSide container.
I loved this blender when I first got it. However just four months after my purchase it started acting up. It stop blending the way it use too. It also got louder then it originally was which scared me. I followed all the steps in the brochure to get a good smoothie but nothing was working. I thought it was just the container but turned out to be the motor as well. Of course I'm overseas and Blendtec does not honor the warranty outside the USA.
this is phenomenal product. YOu can blend everything, nothing is wasted. In very short time, perfecct but simple design. I blend now everything, combination of fruits, begetable are endless with this device. it there is any issue it is bit loud but if you see what work this device does in very short time  that is more than understandable.
You won't go wrong with either one, and I've heard Blendtec is better for soups and programmable features. All I cared about was smoothies, and the Viatmix seemed to handle a mix of random ingredients better than the Blendtec.Final results:Blendtec-Pros: easier to clean, better pour, programmable features, smaller shelf footprint, value, warranty.
When I found out that Costco.com was selling the Blendtec online for just under $ 400 including both the FourSide and WildSide Jars, that was to good to pass up. To purchase the VitaMix with both the wet and dry jars at the Costco roadshow, it would have cost close to $ 500.3) Manual (VitaMix) vs. digital (Blendtec) controls. Personal preference.
What I really enjoy about this is the dedicated buttons, no guessing switching, changing of different knobs like the Vitamix. Just hit one choice on the pad. Also keeps track of your uses with a digital counter that also gives other types of info about the blenderRecommend
What I learned is this:--- For the Total Blender model, there are 6 pre-programmed automatic cycles, for smoothies and other recipes. If you go to the Blendtec website you can view the owners manual for the blender and it has a nice illustration of each programmed cycle, showing how it speeds up and slows down over time for each program.
We purchased our Blendtec last year, 2013, and love it. We use it mostly for fruit smoothies, but have also used it to make bread, salsas, ice cream, peanut butter and almond milk to great success. We would buy it again.
Vitamix 5200 vs. Blendtec Signature Series Blender (with wildside and twister jar)How they compare and rank for me:Prices (at time):1.) Blendtec is about $275 during hot promotions (Kohls) for blender and two jars.2.) Vitamix is about $300 for refurbished, $375 for new (one jar).Value:1.) Blendtec is cheaper, has a better warranty and includes two jars.2.)
This thing makes the best smoothies ever! My kids now have a fruit smoothie everyday after school. I would never have been able to get them to eat that much fruit in a week. Blendtec rocks!
Answer: The WildSide jar is 90 oz.  The Blendtec website http://www.blendtec.com/products/total_blender_classic_combo?gclid=CMOJ0qr7kbwCFepDMgodVD4AIQ states that the WildSide jar is nearly 3 quarts; one quart=32 ounces
