I love wearing my hair straight. It’s so easy to handle and It’s just cute. I usually just use regular flatirons, but i just hate the process and the results aren’t always how I want them. So I tried the InStyler yesterday. I absolutely LOVE it. It actually took less time than a regular flatiron. I only had to go over the pieces once and it was super easy. I didn’t add anything to my hair and it looked really polished and it was soooo soft. It doesn’t crush and damage your hair cause it has bristles on it and the heated part rotates. Another thing about this is, you don’t just have to straighten your hair. It can curl it and flip it. I was playing around with it and I flipped my hair a little and it actually came out cute. I was surprised cause I suck at flips and curls. But I was feelin’ it. hehe. I only used a flatiron to get my edges because I didn’t wanna burn myself. And the only bad thing about this is it makes a noise while you’re straightening your hair. It’s kind of annoying, but it’s not that bad. Overall, It’s so worth it. You can get the InStyler here.
Here is a picture of my results: 
I also have the InStyler, it is quite good but it’s not my fave to be honest. It’s not hard to get burnt using it, the noise like you said is quite annoying & maybe it’s just my hair, but I don’t think the results are as good as a flat iron. It does take less time, but I prefer just using my flat iron then running the InStyler through my hair afterwards, my hair looks extra good then!
