Product review (5 stars): Yes! Perfect!
Though the belt is nominally for a different brand of dryer, it was perfect for our Sam-Sung(as advertised).  Once we figured out how to disassemble the dryer for access, and sort-out how the belt should serpentine around the pulleys and idler arm, the belt fit perfectly; once we figured out how to reassemble the dryer the dryer ran perfectly. It has been running perfectly now for over a month of regular use.

I write this because I use these amazon reviews to shop objectively and want to contribute too.  Thanks y'all for doing the same.
