I think legally they have a standing. Their warranty terms don’t cover cosmetic damage or wear and tear. That’s why they don’t replace the filters or parts that are scratch. Neither actually stops the product from functioning. 

Frustrating as they had offered the replacement and then cancelled it. They might be within their right to, but it’s got to leave a bitter taste in your mouth. 

Paint peeling from mine also, very disappointing because this is an expensive item and it looks cheap tatty now. Dyson need to look at solving this.

Mine is the same, I have had it for some time now but the pink parts scratched shortly after getting it. I was very annoyed with this but read that it’s not covered by warranty, even cheap hairdryers don’t scratch. 
Hopefully they are using better quality materials for the new version, though they shouldn’t have scrimped on it in the first place when it’s the most expensive on the market. 

Always was a ghd dryer and straightener user never any problem with peeling or looking unsightly and half the cost of Dyson, very very disappointing. Certainly won’t recommend as regard value for money.

really gutted to see that paint has peeled off my Dyson. Like the other comments above said even cheaper hair tools on the market don’t have this wear and tear. I’ve only had the Dyson for under 2 years. If i had known paint chips off like this then i would have bought a dustbag as the case takes up too much space
