I purchased the the 64 oz Vitamix container to replace the original one from when I first purchased my Vitamix 7 years ago.  Im very pleased with purchase as I use Vitamix twice every day for smoothies and have been almost everyday since purchasing it 7 years ago.   It is still running strong as it has on the first day.  When it stops working I will not hesitate to buy another.  I am Vitamix customer for life.
