By far, this is the best blender I've owned.  As other reviews have stated, there are plastic parts that may decrease the lifespan.  However, the ability to create custom smoothies quickly at home means it will pay for itself rather quickly.  I buy fresh fruit and freeze in quantity (muffin tins provide perfect portions), so it takes only a few minutes to whip up a breakfast smoothie with uniform consistency.  Fruit granitas are a favorite dessert, ready in minutes.  Wish I'd bought one sooner...
