VIVIR straightening brush

I bought this straightening brush months ago and have never used it. It works perfectly fine and gets very hot. I tried it out once and it just didn't work well with my thick hair. If you have thinner hair this would seem great. Impulse buy that I regret spending $100 for something I never use. $50 OBO willing to negotiate here is the website to the product https://www.vivirhaircare.com/products/vivir-hair-straightening-brush
