Trying to get a quick return over such a machine since the effects are felt on the length. But the effectiveness of pulsed light is there. My wife uses two years of another model from another brand. So this is my sister-who had the task of trying one. One can only recall the cons-indications of such a device. This is not trivial and should be read long instructions (and therefore to learn in advance) before acquiring this kind of gear. The handling is not optimal with respect to a model to handle hair dryer type, but well enough for small areas and the price well below the model then advocated the Babyliss G932E. Favorable opinion so even if it is confirmed in the long term.
