Bought this dishwasher to replace a 7-year-old 800 Series model that broke sooner than I'd have liked.  The major upgrade of this model is the CrystalDry technology, which actually does seem to do a good job of drying, especially of plastic items. The main downside is that the layout of the three racks and silverware container seems less convenient than the older model, and as a result we seem to be running the dishwasher a bit more frequently.  The WiFi app is not all that useful, although it is sometimes nice to be alerted when the cycle has been completed.  I'm hoping this one lasts more than 7 years.
