Product review (5 stars): Whirlpool Duet Front Loader Bellow:  Great fix!
Fast shipping. New.  Saved me from buying a costly repair or new washer.  Used this on Whirlpool Duet front loading washer, 2010 model.

Big-Box store was going to charge me $195. for the part alone My brother (who is very "handy") watched a you tube video & was able to install in under an hour (time includes getting tools and set-up).  Big-Box store quoted $275 for labor.
