Small but a lot of power. Who is worthy to very hot blow drying should possibly take another. But to hot blow drying is bad for the hair / extensions. Has two power and heat three stages. Highly recommended for little money. The design is unbeatable anyway, my girlfriend was very happy. Goes through a travel hairdryer, although we use it as Hauptföhn, need to hide from the performance ahead of any large hairdryer. Thumbs up!
