Great product! 4C natural hair
I have used this product twice.  I have 4c textured natural hair.  Have never used a hair straightener.  Used it at 370 degrees F.  Straightened relatively medium-sized sections of my hair in 2 passes.  Took me 20 minutes to finish my head.  Passes through so easily afterwards that I passed it through all my hair as I would with a regular hairbrush.  This is not recommended by the manufacturer btw, but I wanted to try it anyways.  Hair still has bounce afterwards and my ends are not stringy.  Look at this temp was between a blowout and flat hair straightener finish.  Heats up quickly (takes 5 minutes to fully get to temp).  You can feel the heat emanate from the brush as it heats to temp, but the black spokes do not get hot (only the ceramic portions).  Comes with 2 alligator clips that have amazing hold!  Did not need the glove provided to hold the product.  My only complaint is that the brush is hard to clean thoroughly when product in my hair materialized on the brush.  I had to use my pressurized keyboard cleaner to clean the crevices for my next use.  If the product came with a soft bristle brush with bristles long enough to reach the bottom of the brush, I would be completely satisfied with my product and give it 5 stars.  Would definitely recommend for straightening natural black hair.
