I have ordered several other discounted belts that claimed to be genuine and they failed miserably. These belts didn't get my brushroll to rotate. I thought I had a problem with my brushroll, it was actually the belts. I never thought belts could be so important. What's the real difference. These straps are really real, they are much stronger, thicker and excellent quality. Do not buy discounted belts anywhere else. This is the way. Thanks for a great product at a reasonable price.
