Instyler Rotating Iron

I use the Instyler on my mom's hair, in conjunction with a flat iron for the roots, and it works great. She is all natural. I like the Instyler versus a flat iron because it leave it with my body but still silky straight. I blow dry her hair first and then use the Instyler. I've used the Maxiglide in the past, and it did absolutely nothing for my hair. I've been feigning to use my mom's Instyler though. She's had it for over a year, using it quite often, and it is still working perfectly.
