Product review (4 stars): Worked great for 6 months
After 6 months of light use, the circuit board on the washer died. That was around December 1st. The service folks have been great, but the replacement part is on backorder, and every time the service company calls the manufacturer to see what's going on with the part, they keep getting a different date (further and further out) that it might be available.  At first it was going to be available in around 2 weeks. Then it was another week or two. Now the current projection is that the part won't be in stock until the end of January - two whole months!

I haven't tried to call Whirlpool to complain to them yet, but judging from other comments, I'm not sure I need the exercise in frustration. If I do, I'll update this.

I read some of the negative reviews here before I bought my Duet pair, but the sale price for the set was about the list price for a single piece, and I decided that I couldn't pass it up - so I purchased the extended warranty. But the warranty isn't of much use if the parts aren't available.  :-/

Since this has transpired over the holidays, I'm willing to cut the mfg a little slack, but 2 months is unacceptable! My next W/D will be top loader & manual dial.

UPDATE:
After it was fixed, it worked great and I was sad to leave it behind when we sold the house and moved. It's over 3 years old now and never had another problem. I'm upgrading to 4 stars - I still have to knock off a star for the defect and slow repair time. But I came to love it.
