Hi, this is my tangle teezer. They were launched after the idea came about in dragons den. you can buy them in multiple colours. The great thing about this brush is that because te brush is made up of all different sizes , you can pratically remove any type of knot. I've had brushes in the past which haven't got rid of some knot. Also is doesn't hurt. The base is curved making it easier to brush your hair since your heads also curved. The prices range from £6-£12. It depends on where you buy it from and if it's a limited edition brush. I would rate it's a 8/10.
Hope you had a good Christmas :)
