This is the HP 8663 model You must have washed your hair and dry them with a towel before use. With the flat brush for smoothing heating is not bad. The one with the tuck pins is nice to make small waves, it depends on the nature of the hair. Then the big thermobrosse diam. 38mm I like less. It's simple 3 brushes and nozzle are clipped very easily. The handle is very nice in hand with an electric wire of 1.80 m by turning pivot, (great) a tether suspended for 3 different heaters, two-year warranty Made in CHINA! Designed in the Netherlands. Ionic function to make hair shiny, smooth and frizz-free.
