Product review (5 stars): One week and....
Only had a week so far but laundry was backed up because our old one broke.  I have 7 children making a house of 9.  We've, so far, put this washing machine to the ultimate tests and it has conquered with ease.  Absolutely quiet, washes extremely large loads, and clothes come out near dry and super clean.  Very impressed...
Dryer works just as well drying extremely large loads with ease.  I am amazed, thus far, with the performance, ease, and luxury these appliances have.
I was skeptical about the twin wash for the bottom but will say it does what it does so we'll.  It is also quiet and works very well for small loads.  I have already found realistic reasons to use it like last minute work or school clothes for one or a few people.  I say realistic because we have used it just because since we have it to make more wash and catch up.  But sincerely, it has been worth the extra money.
As far as WiFi and app use we have not done any of that yet.  Just simple touch and go so far.

Warning.. All you great men like me who know how to set up appliances without instructions.  Don't forget tk remove the 4 shipping bolts on the back of the washer.  They look built in and you might be like me and leave them and during your first wash you'll wonder why you machine is bouncing all over the place.  There's a big warning that says, remove shipping bolts.  Oops... Anyways, once removed the machine was smooth and quiet.
