Review on Kirby Vacuum Cleaner Belts 301291 - Compatible with Generation Series Models G3, G4, G5, G6, G7, Ultimate G, and Diamond Edition - Pack of 6 Belts by Susan Vaughn

These belts were a nightmare. They do not serve properly and break very often. I am not sure if they are old but they are very fragile and short lived. I've changed the belt more times this year due to a broken belt than in many years of owning a Kirby. I will be shopping at my local vacuum store from now on, I just can't rely on ordering belts for fear they might be old and brittle.
