I was excited to receive the smaller container and it did not disappoint.  The 48oz size is perfect for making smaller batches of smoothie and recipes without having to use extra ingredients than the portion I need.  I love the ease of use and also cleaning as well.  Compared to the 64oz container, it is easier to clean as well.  I am able to make my smoothies more frequently and also fresh each day instead of drinking an older batch due to blending too much at once.
