Lots of bells and whistles with this machine. Actually I felt a bit overwhelmed initially.  but after reading the manual and checking things out further, it is fairly easy to use.  A wide variety of settings allow you to customize your wash cycle to suit your needs.  Normal, towels, bedding, activewear for all your gym things, and a sanitize as well.  The top washer is perfect for smaller loads and delicates. It can run at the same time as the lower drum, which can handle large loads to get laundry done fast.  Offers a foaming wash for a deep clean.  Energy Star rated to help keep your electric bill low.  Runs quiet and has a little jingle it plays when the load is done.  So far so good with this lovely Samsung washing machine.
