Product review (4 stars): Good Product; Be Wary of Supplier
I bought this belt through Amazon to repair a DV218AEW Samsung Dryer. The belt came in good condition, was easy to install, and is still running nicely.

However, I initially bought it and it was shipped by Reliable Retailer. That belt had a 2-week estimated delivery frame and it missed it. Reliable Retailer issued me a refund and sent me on my way. I then bought it to have it shipped by Samsung Parts, with a similar 2-week delivery window, and it came 2 business days later.

The belt is a good replacement for the above mentioned Samsung dryer. Just be aware of what company is distributing the part.
The belts do seem to wear out over a few years, much faster than on the older dryer models.
