I have had my InStyler for over a year. In my opinion works just as good if not better then a regular ceramic hair straightener. Whenever I style my hair with the Instyler my hair stays styled for the whole day without having to touch it up once. The rotating iron and the brush attached to it get my hair super smooth, and very volumized as well. My hair even looks really shiny afterwards as well. Now for the downside. Although the Instyler makes my hair look really great, even with the heat protection I use, it has given me a lot of split ends. Over time it has made my hair very prone to breakage, dry, and fried looking. I know you can get damage from any hair styling tools but I feel like the InStyler has made my hair much worse, because it uses such high heat and even at the lowest point it is still very hot. I wish they had the option like other hair straighteners to choose the exact temperature you want to use. I still use my Instyler, and it still works very well, but I only use it in moderation and not as much as I used to, because the damage can get pretty bad. Effectiveness It does a great job at styling and straightening my hair. The great thing is, is that the style holds for the whole day, so it works amazing in the styling aspect. The bad news it that the Instyler has caused a lot of damage to, and fried my hair. It gave me more split ends then I ever had before, even if I use a heat protectant. I've never got as bad of split ends from another hair straightener before. Durability Although it doesn't look like it would be very durable, and the plastic looks cheap, mine has held up very well even after dropping it. I have had mine for over a year now, I use it almost everyday, I have dropped it on several occasions, and it is still going strong. I haven't had any problems with it whatsoever.
