They work and they are cheap.June 7, 2007 Greg Bosworth(Dawsonville, GA USA) 5 out of 5 found this review helpful
Did you try to wash your tribest blender or griding unit in the dishwasher without reading the instructions like I did? Did the O-ring seal become loose from the heat and subsequently fall into one of your shakes and get shredded like mine did?
If you answered yes or nodded your head while reading the above paragraph, you're in luck. Just buy these and you can replace the seal with no troubles.
4/5 stars because it would be nice to just wash the blending units in the dishwasher without all the hassle.
