What's a really good one? I've had three, they always seems to stop working after 1 year. I've had the Conair Ceramic, Cricket, and Solia pink limited edition. My hair is relatively straight, I really only want it to smooth out a few waves and kinks. I know the CHI is good, but its expensive and I heard that it damages your hair because its at really high heat and you cant adjust it. I'm willing to pay the price though if it will last longer than a year. Any suggestions?
