I am completely blown away with this flat iron! I have very curly, coarse, ethnic hair and have always had a very difficult time getting and keeping it straight. I bought the Karmin G3 after reading reviews and am very happy with this iron! Although because of my hair type it takes a little while to straighten my hair complete, the Karmin is much faster compared to irons I have used in the past however the best part is my hair stays straight til I wash it next with only a few touch ups in between. Best flat iron I have come across yet and the only one I will ever use!
