I think that it really depends on your hair type. I used a CHI flat iron on my hair for years thinking that it was the best for me until I tried my sister's GVP iron. Her GVP not only straightens my hair quicker at a lower temperature, but it also costs half the price! It causes less breakage on my hair and leaves it shinier and smoothr, probably because I don't have to go over the same parts of hair as many times as I had to with my CHI. I can see the CHI working extremely well on people who have soft, looser curls or fine hair. My hair is very curly. I have very tight, tiny curls.
