Very good quality construction. The ionization function reduces frizz. It has 3 types of nozzles. The cord is very long. It can be used for professional use. It lacks an air setting between 1 and 2 that is a bit milder. The difference between setting one and two is significant. An intermediate setting would be perfect.

I have the Valera hairdryer for over a year. I researched it a lot before making this purchase and I can say that I am very satisfied.
I have long, thick hair that easily frizzes. My hair dries very quickly and in ten minutes it becomes straight and relatively smooth (I mention this for someone who is too lazy to straighten their hair properly). The hair does not get damaged even at the highest heat setting. The ionization function (recommended for my hair type) helps reduce frizz. It has 3 types of nozzles and the cord is very long. I believe it can easily be used for professional use (even though I am not a professional myself).
There are cheaper options available, but the quality and the result are definitely worth 100% of the purchase price.

While every time I use it, I feel like the air it produces is not powerful, ultimately it dries my hair very quickly every time! I had Valera before and I recommend it!

I wanted it to be more powerful, I expected it to blow my head off with the force of the air, but compared to an older (13 years old) Singer model, it doesn't have much to say. It's not noisy.
Update: the temperature of the hot air is incredibly accurate! It doesn't burn you, it doesn't burn your hair.
I use it to dry my 13-month-old daughter's hair without being afraid of it getting burned!
