Input:
This blender does a wonderful job of blending an ice-cube based smoothie until it begins to leak.  We have replaced the gaskets once and the blade assembly once in less than a year.  It works for just a few days before it begins to leak and the nut and bolt has to be tightened with special tools including channel locks and socket tool.  The idea of reaching down into the blender with a dish cloth to prevent cutting one's fingers to tighten the thing is baloney.  I never know when it is going to leak until I set it on the housing and smoothy mix begins to flow out--what a mess!  If I could find a blender that worked as well without the leaking, I would buy it in a minute.  I certainly would not recommend that anyone buy one of these Waring PBB212 bar blenders.
