They lent me another opinion 2 airflows and I liked already. With this one is even better. Convenient its 3 levels of airflow. Lets stripped in no time old paintings. And without fatigue. Most of the time, I use the second level of air because that is enough for the majority of paintings but when I want to go faster I put the 3rd level. In addition it is very light and no noisier than a hairdryer. I adore.
