It seems to be the one QVC last sold as a TSV which the problem is with. Quite a few on QVC Facebook page freaking out with worry, and people telling them to contact CS and return. Not sure if that one was made especially for QVC???? As the same kit has been seen in Boots are a good price, but the normal red colour.
As said earlier in this thread I bought a new hairdryer(not this brand), mentioned to my hairdresser how it did not seem as hot as the old one. The air flow and heat on Med(I always keep on Med), on my old one was a lot hotter. She told me that meant the old one was coming to the end of its days, they get hotter it seems when the engine is starting to go.
