This Stainless steel container is fantastic, I love the smaller size and really love the fact that it's stainless steel it's made really well and is heavy enough to hold in place on it's own.  I can start my blend and just let it finish.  I get perfect smoothies every time with this container. I do have the Accent series blender and this container doesn't auto-detect (that would be a nice feature) however it still works fine not the preset settings that are on the blender for my smoothies. I use this daily.
