This device is very powerful, it even smooth frizzy hair perfectly and quickly. Only big problem, the main brush, for the big thick and long hair. It deteriorates immediately. I bought this camera has almost nothing because of the brush who loses the spikes, you are at the end of two months with a smooth brush. Therefore unusable. Since I buy just the accessory to the internet, so that the brush already costs 20, so pay attention, plan the purchase of the brush part detached very quickly.
