I wanted to buy the 500 series dishwasher but was forced to buy this model because of delivery details, but I must say I am very happy with the purchase.
There is a lot of room in this dishwasher for all my dishes, the adjustable middle rack is surprisingly helpful when it comes to tall dishes and bottles, and the top rack for spoons is very useful as well.
It does connect to wifi and my phone and sends alerts when rinse aid is low or when the wash is complete.
Unlike my old Samsung, this has a removable filter which is easy to clean.
All in all, this is a great dishwasher and would definitely recommend.
