Title: Thread is too deep.
Review: I purchased this to use with 12oz mason jars and found that it does not thread onto the mason jars, and I tried several brands. It is a little difficult to screw onto the blender pitcher and the threads run a little deep preventing an adequate seal with the original gasket. It may work better on other pitchers.
