The first strap in the pack of two broke almost immediately after installation, a few seconds after first use. The second belt broke on the next use after a small cloth got caught in the agitator. I have a Hoover Widepath Tempo (a very common base model) and found the strap installation unreasonably tight. It fits, but after a lot of effort tried to stretch. The original belt has served me for years with similar usage. I'm not sure if those tires are old or what but I was expecting a bit more.
