Works good.  Apparently there is some confusion on how this goes on. On models without a plastic rim that closes into gaskets- this gasket needs to be applied with the sharp rubber edge facing towards the door instead of facing towards the tub sides.  Works great when installed this way.  Make sure the bottom of the kerf where this fits into is nice and tight.  Sometimes removal of old gasket pulls the kerf tab out and makes this gasket loose at the bottom. Pushing the kerf back towards the tub so the rubber remains snug makes it work great!
