I purchased this straightener when I lost my original one moving. BIG MISTAKE. My other one was the exact same size and straightened my hair in less than half the time. This one simply does not get hot enough to straighten my medium length, thick, and wavy hair. My hair isn't even warm after running the straightener through it. Because of this, I waste so much time! If you have thin or short hair, it might work, but I would still suggest trying a different product.
