This hair straightener definitely worths more than 30 dollars, to tell the truth. The appearance is good design as it has a white color, which I prefer. And it heats up really quickly (also cools down quickly when you turn it off), really convenient. I like it that I can adjust the temperature easily. And it won’t hurt your hand when you do the hairstyle because the thick protector. And I use it to straighten my curly hair, which works pretty well.
