I have owned a HD01 hairdryer since xmas 2019. I wash my hair about twice a week and have always cleaned the filter before each use. Recently the power has been cutting out when using the highest heat setting. I rang to get it serviced and was told they would only speak to my husband, he then had to call to state that he was happy for you to speak to me, so on my second call I was told that you could arrange to collect and would look at it but it would cost me £100, which would be returned to me if you couldnt fix it. I had my last relatively cheap hair dry for 8 years, it was only replaces because of this rather nice xmas present. 3.5 years is not nearly long enough as a life span for this piece of equipment to last. I am truly disappointed at the extortionate cost of getting someone to look at it, it is clear that the static metal filter screen needed a clean, this must be a common problem!
I brought a dyson screwdriver set from Amazon, and have cleaned it myself; it took me 30 mins in total.
This hairdryer although lively is not worth the cost, the filter is not adequate and it is disgusting for you to charge £100 for a service.
