Don't know about the product quality but I received an out of order piece. It was getting switched on and there was a cut in the wire. Dear supplier, please check before selling. Don't try to loot people.
Not very long lasting . Just fine for few hours. Then ur hair comes to natural. Not worth for so much money.i had hair fall also when using the brush. The pack was also not so good. It felt like used brush. Don’t get cheated
