This blower is supplied with 2 brush diameters, 36 and 50mm. Special feature: the 2 brushes each have a colored protective plastic housing very solid, easily removable and very protective capabilities: really well thought out. A narrow concentrator also comes: it has a drying capacity since concentrated on localized air opening on the side. However, this tip is for use in case of need rather quick drying, it will do this faster than the brush operation. Whatever the chosen mouthpiece, it fixed and removed very easily. At the end of each is a small slider, in a sense it blocks the tip and on the other it unlocks: efficient and simple. The cord is rotating, practice. Comes with a cover and we arrange it easily the machine, the brush of his choice and the drying nozzle if necessary. By tightening all, one can also house the second end cap, but everything is in pain and too wedged inside. The ionic function is activated automatically as soon as the ignition of the brush. A correction is made to the description from Amazon: This brush is not drying has 2 speeds. However it has 2 good temperatures, in addition to the fresh air position, which is rather very warm and pleasant to attach the loops. A green LED located near the button shows the operation of the brush. It also has a second button at the base of the selected brush arm or tip: by pressing this button and applying the desired direction to form the loop, and keeping the wrist firmly, brush accompanies the rotational movement into powering the arm slightly but sufficiently to complete. One only has to hold the brush in one hand and the tip end of the other brush rotation detect the direction we chose when we started closing the wick applying a half wrist size. In fact, you get used to very quickly. The brush is of a significant size slightly, but then it has a quality engine and fan is very effective. The noise emitted is correct, much weaker than a standard hair dryer, but present nonetheless. The weight is light even if the size seems consistent. The filter is located at the back will toggle the grid whose hinges are secured to the body of the brush and easily extract a small fine filter is being cleaned.
