Review title is It's Ok, but design flaws call for improvements [SEP] Although this straightener brush is good quality, it's not very ergonomic. The handle is too long, and the head of the brush is to large to properly comb all areas of the scalp effectively. The bristles also don't conform to the head shape well. For some reason they thought it was a smart idea to make the heated bristles in the middle stick out the most. Big design flaw. It straightens Ok, not great. I have wavy dark brown hair. The brush seems less effective with dry hair. Try using Aragon oil. Overall, not really impressed.
