Product review (5 stars): The seal is held on by a spring-compressed ring that you will come to dislike very quickly
Replacing the seal is not a trivial matter, but you can save yourself a hefty fee from a repairman if you have the confidence to tackle the job yourself.  I replaced the seal on our front-loading HE washing machine after it got a large cut in it somehow and the only cost was the part and about 30-45 minutes of my time.  You will have to disassemble your washing machine to replace the part, but it is not hard.  Just pay attention when you remove the front facing, as the plastic tabs can break and then you won't be able to get the face to hold right.  The door doesn't really need to be removed, but I removed the door to get it out of the way.  The seal is held on by a spring-compressed ring that you will come to dislike very quickly, so be ready for a bit of a trial at the end.

Since this is about the part itself, the rating is 5 stars.  Our washing machine is like new again and it didn't cost much at all.
