Query: Stay away from this product!

I bought this flat iron as a gift for my girlfriend. She has thick wavy hair and usually flat irons her hair. The iron stopped working after one use. It seemed like the unit was not getting any power. This is not the quality one expects from such an expensive product. The manufacturer does not provide any warranty if the flat iron is bought online, but I am glad I was able to return it to Amazon.
