As you would expect from Miele, very well made.
I do have to say, that as a mechanically minded person, this is the 3rd washing machine door rubber I have fitted, but the first to a Miele, and definitely the hardest to fit, in that you can not fit this through the front hole, like I have done on previous non-miele washing machines I have worked on. Even taking the top off the Miele washing machine is like no other, but once I worked out how to get to all the hidden screws, and get the top and front off, it was a fairly easy job to fit the rubber seal.
We now have a non-leaking washing machine again.
