I've read mixed negative reviews, sometimes they seem to work and sometimes they don't. I rolled the dice and the small belt works as expected **see edit**, the large belt doesn't even stay on for a few seconds, it pops out as soon as I turn on the vacuum, I opened it up and tried 4 different times, um forcing it to work before you give up and just put the old wide belt back on and voila the old one works and stays in place which tells me something is wrong with the new wide belt! **EDIT Right after I put this in I used a vacuum and noticed that even the small belt doesn't work properly, it's too tight and even upright, the roller brush is still on and spinning so two belts don't work!
