I have a 13 year old Dyson and I bought it to complete the overhaul I was doing on it. The part fitted well, but the drive belts supplied were a bit small. I contacted the seller and he immediately sent me the correct belt sizes. The only reason I plan on not buying this again is that I should probably buy a new Dyson, but if you're cheap as I am, buy it and hopefully it will last another 13 years.
