Product review (4 stars): Best price with decent shipping for this replacement part.
I have had to replace this twice on my washing machine. It is by far the most fragile part on my front-loader. You must pull open it to check for socks and whatnot getting caught in it. It can be fairly easily torn. This is the primary part that keeps your floor from getting flooded.

This part seems to be of similar quality to the original. It is not too difficult to install when done properly. While less expensive than the original replacement part, it still seems overpriced for the materials.
