Product review (4 stars): All the duets take some getting used to
There is a lot to like and a lot to make you nervous.  if you use the washer for hand washables, wool, cold water washes with high sudsing detergents expect WILDLY varying time estimates.  Wildly:  3 Minutes > "sensing" 42 minutes > 41 > 40 etc back to 9 minutes > "sensing" > 22 minutes... etc.  Not broken, just very suds sensitive.

The seal is tight, good, but mold can grow: bad.  use an acidic cleaner when recommended.  Learn to do big loads in a couple modes.  Example:  Quick wash whites on short cycle cold wiht a dot of cold water HE detergent.  Then restart the machine on quick wash normal and do them again HOT with a touch of bleach and detergent.  Expecting guests:  Run them one more time on quick wash hot with peroxide (oxy clean).  Blazing white, clean, best job ever.  When the guests leave, do the middle wash on sanitize.  Sweet.  BIG loads.  Less water.  The need to be smarter than your machine.  You can do it.
