I was thrilled when I found 20 belts at this price. However, sometimes it's too good to be true. I have used ALL but two belts in the last year. Every time I put on a new belt, the belt breaks after 2-3 uses. I have a very small house (900 square feet) so it's not like it's overused. I've never had a problem with original Kirby belts. They seemed to last forever. You can imagine how this increases the need to change the strap frequently. That doesn't mean you don't have to disassemble everything to do this. Lol This is NOT value for money especially since each strap is only used 2-4 times. It's just frustrating and frustrating.
