This is truly a single-pass, get a great curl, curling iron. The twist handle to increase, decrease or turn off is very nice feature, as is the extra long cord. Highly recommend this curling iron and have been very happy with all of my T3 purchases!
I was a user of Conair products, but I did notice that if I blow dried my hair prior to curling, the curls always fell out. With this curling iron, they stay curled which is fantastic. It grips the hair really well also. The only negative comment I have is that I use the curling iron on the highest setting due to my extremely thick, curly hair and the top of the wand that you hold does burn my fingers once in a while. But other than that I love it!
I like the size of the curls that this curler gives me. I do have to use a good amount of hairspray otherwise they fall almost immediately. The only thing is that my hair smells like burnt hair which is what another review said even when I use thermal protectant.
