So far, so amazing. It works very well, our clothes have never looked so good; at least compared to the old machines. Really like the "one hole" concept of the all in one device. Not having to remember to load the dryer, etc. 
The build quality is excellent, this is a substantial device. The user interface is easy to navigate with a large amount of choices. The energy and water usage is incredible. It uses so little of both you wonder how your clothes come out so clean and dry. It does take some time to do a load with the full AI economy engaged. We expected that and it is not an issue for us.
I would recommend the Samsung device without hesitation.
