Review on Brentwood Replacement Coupling Osterizer Blenders by Michael Crossman

This thing broke 20 minutes after installing it. Has the rubber part detached from the lower threaded part for some reason? I don't know why but waste of time, I bought another part from Revain and it worked! Stay away from this one, it has negative reviews for a reason. I bought a "Blendin connector bolt guide pin kit compatible with Oster and Osterizer blenders" and you know it's no problem.
