Works great for thick hair straightening lasts for days unlike others, I have tried so many and this by far works for my thick hair it's amazing only 2 complaints I have is I like to use my straightner to make beach waves so I wish this had a thicker shell and it does snag hair just a little but even with those two issues I still love it, I don't even use it on the highest heat and it works awesome I'm 52 so I've owned many straighteners in my life lol and this is by far the best for my thick hair I've had Chi and KARMIN to include a few that I've used
