This dryer is a game changer for me and my family! Never have I had a unit that could dry a load of clothes in 42 minutes! With the10 Preset drying cycles, we are sure to protect our clothes from heat damage, over drying, and using more energy then we have in the past. I do suggest when drying towels to use the timed dry setting. When I don't my towels are not completely dry. I have not been able to get the machine to connect to the app yet. I have other Samsung smart products that I have been able to connect however, both the washer and the dryer will not connect. It sounds interesting to be able to get a diagnosis and be offered quick solutions if the dryer is not performing.
