I have had this blender for about 1 1/2 years.  We use it to blend soap so it does not get consistent use.  From the beginning it would stop working and if we waited a while it would work again.  A safety feature I guess.  Over time it stopped working instantly and now it will not blend yogurt.  This was a replacement because the first on did the same thing.  Maybe it is not made for what I am using it for.  Cheap ones seem to work fine but I wanted an upgrade so I purchased this.
