Product review (1 stars): Is this a new version of one I've had fail twice?
I am not sure whether to order this or not.  The original came with my new InSinErator purchased 12/2012.  The inner rubber gasket failed and the company sent a new stopper 9/2015.  Now that inner gasket is stretched out and will not hold water.  It takes at least 5 minutes to replace the gasket in the slot.  I cannot tell if this is a new design without an inner gasket. I contacted the company who think "possibly your stopper was affected by chemical or abrasive cleaners."  Not possible. I was told there is no replaceable part with the stopper.  I went  to local stores and this model was not available.  So I guess I'll keep using a sandwich bag to make it seal completely.  I think 2-step stoppers are worthwhile if they last.
