My stylist uses the T3 iron when I go to her and that one is great...I also think she just has great skills with the flatiron also...lol.
At home I have 3 flatirons--I have a Solia, A Hai Copper Tourmaline Iron, and I also have a Regular Hai Stix. I've also tried Chi---didn't really like it.
I've found that I use the Hai Copper Tourmaline the most (I only use it once per week on my hair). It's fabulous. I've had it for about 6 months now....leaves my hair silky and smooth and I have very thick, natural(no chemicals and no color), below shoulder length hair. No breakage or anything..my hair is naturally healthy and using this iron hasn't affected it at all...
