I've just completed 30 washes, and the reason I know that is the app reminded me that it was time to run a tub clean cycle.  After some initial issues getting my washer connected to the WiFi, I was able to connect and that part works great.  As far as the washer, I love it.  There are a lot of different settings and options.  I think I use less detergent and my clothes are cleaner.  I also think the regular spin cycle cuts down on my drying time.  I switched from a top loading machine to this model and I'm glad I did.  There's a little extra maintenance to this machine (wiping it down after I'm finished with laundry).  I really like this machine and I really enjoy the app feature.  So far, no mildew smells and my clothes come out clean and fresh.
