This is one of the few actual "whole jar" kits you can find out there. My wife broke the old jar and threw all of it away which is troubling since we could have just purchased a jar and re-used all the other parts. Anway, this jar fits the beehive oster blender perfectly. My only complaint is that the lid has a very high VOC odor so if you leave it on the jar overnight, the jar will be filled with that odor and presumably flavor whatever you put in the blender as well. I have taken to simply leaving the lid behind the blender and only putting it on to start the blender. My hope is that the odor will decline with time.
