The vacuum belt I ordered was part of a Gates 153-3GT-8 Shark vacuum. The belt I received was #3M-180-6.5. In fact, they're not even remotely large; not even close to working. I hope this is not indicative of what will happen to future orders. One product is advertised and another shipped. I really need my vacuum to work as it's too expensive to buy another for a $2 belt. CAN SOMEONE HELP?
