Powerful, Not too noisy, The diffuser soft spikes: the top for my curly hair! And it changes the hard spikes that are a headache! Flux concentrator: nothing special. It's not bad. Heat "preset" is great: not too hot, not too cold. Button cold air: here ends well capping. Turbo Key: here useless but funny. Ionic ON / OFF function: I feel it's not bad, little or no frizz, it changes.
The "minus": it is imposing, but it is a beautiful machine. We must not expect the lightest device market, but very acceptable weight level.
Let's say for the price, it is a very sophisticated device and very friendly to use ..
