We bought our dryer with the washer as a set in January of 2024.  The machines perform as expected.  We have never used the steam sanitizer function and are not able to comment on the function.  Will try to explore in the near future.  We have been fans of Samsung products for decades from cell phone, TV , kitchen appliances and washer and dryers.  We are comfortable in selecting Samsung products due to our trust relationship with the brand name.
