That's it really. I have a Dyson upright dc24 ball which we were given as a wedding present by bro&sis in law and I was so excited to finally be getting a proper vacuum cleaner, and a Dyson at that, and just assumed it would be good quality and would last for 10 - 20 years.
We had so many problems with it in the 5 years it was under warranty that they actually replaced the head on it as apparently that model was riddled with problems but it's still not very good at its job and is making a terrible noise and I, possibly irrationally, hate it. But can't afford to buy a new one.
