Product review (5 stars): I will buy this one again
Exactly as the original....... it does have 2 rubber seals as the original.  Seems solid and slipped in easily and made a good solid connection.  It took only about a quart of dispensing before the water was clear and ready to drink.  I would recommend shutting off the water supply first as instructed since that will reduce the pressure needed to seat the filter.  I do  believe that those that mentioned leaking perhaps did not turn the water supply off first... and they did not push and seat the filter properly.
