I don't know the answer to your question but I like what this hair system can do.
Right now I'm using an old T3 hair dryer and one of those Revlon brush dryers. I actually use both when drying and styling my hair however the Revlon one is on its last legs.
I ordered the TS on their flex pay. Yes I broke down and ordered one but it seems like it can do almost everything that I need it to do.
It's the most expensive dryer that I have ever purchased but just getting hair highlighted, etc. can also be very expensive. It's also half the price of the Dyson.
I hope it's as good as advertised!
