Yesterday I had to put the second belt from this order on the vacuum cleaner. The first one broke, lasted less than 2 months! Surprisingly since I live alone there aren't many people in my house and I don't have to vacuum more than once a week. In fact, the straps feel too tight when I change them, even though the product number is correct. Maybe old tires, maybe a broken belt, maybe an accident. But I have no plans to buy them online again. I will be going to my local vacuum shop to inspect the belt before buying it.
