I have had it for about 6 months and I use it constantly, and so far I am very satisfied. I have very fine, fragile hair, so I was looking for something that wouldn't damage it and would make the straightening last, so I wouldn't have to straighten it again and again and damage it. The straightening really lasts a long time. All straighteners damage the hair, but the ionization helps a lot with that. That's why I never use it without ionization. I have also noticed that my hair straightens at lower temperatures and faster than my previous one, which, although not cheap, had to burn it for an hour to straighten it. For example, with this straightener, I choose 170 or 180 degrees if I want it to last (because I don't have thick hair and my hair is straight to wavy), while with my previous one, if I wanted to make sure it would stay straight, it needed at least 200 degrees! So since I started using this one, I have obviously saved a lot of money on hair care products. It doesn't make them frizzy at all, and I can say that even with high humidity, they hold up. It requires a little attention because it burns wherever it touches, so I place it inside its case until it cools down, which I read is so that you can still carry it even if it's still hot. I was spoiled by my previous ones, which I could touch when I unplugged them from the power source on the floor or on a surface to cool down, but this one took a while to cool down and burned my floor. My mistake. The only negatives I see are that if someone wants to use it as a curler because it is flat and somewhat square, it is not possible, or at least I don't know how, even though its surface is a bit narrow. In other words, it covers a larger surface in the length of the hair than in the width, so they straighten little by little. Also, it is not the lightest straightener in the world, but not to a tragic extent like the belissima device for wavy hair, which whenever I use it, I feel like my hand will fall off. Overall, it is worth it.
