Product review (2 stars): Installing it was also not so easy as it looks as the Metal center does not ...
DONT BUY THE ONE WITH METAL INSERT!!!! I replaced the already broken part in March'16 .The previous one was all plastic and I ordered the metal insert thinking it would last me longer. Installing it was also not so easy as it looks as the Metal center does not slide easily onto the motor part.and now its down again making me work again. When I opetned the machine again this week  I saw that the plastic part had several big cracks around the metal insert. I had to go through this again , fixing this for the 2nd time in the last 7 yrs.
