Product review (4 stars): good replacement when your OEM belt breaks
When our samsung washer stopped rotating, we were a bit concerned. Our extended warranty had just expired and the last time we'd called someone in to repair a washer, it was a fiasco. Fortunately, the internet is here. There are many how-to videos on youtube, and websites like iFixit have great tutorials.

This belt works on both the front loading Samsung washer and dryer.

It took my less than an hour to disassemble my front loading washer and install the new belt. The one thing I had an issue with was getting the belt to stay on the track while using the tensioner but still being able to slip the drum back into place. The trick I found was to leave it off the tensioner, assemble the washer, and then remove the back plate at the bottom of the unit. Simply reach in, move the tensioner to the right angle, slip the belt into place, and seal the back plate.

I've used the new belt for about six months and have checked it by hand. No fraying or cracking so far.
