So, I have the full sized blender at home and its used quite a lot! I bought this one to keep in my office. I simply fill the container with my smoothie ingredients and pack it in my lunch bag. at work its in my container in the fridge, and I bring it out when I need a mid day pick me up. its nice and quiet but extremely efficient. I have some co workers who would like to buy an extra container to use,hopefully they will be available soon!
