I have really thick/long hair so straightening it usually takes a long time, but this straightener works so well! My CHI has lasted over 4 years so far. My cousin has had hers for almost 8 years and it's still in great condition.
I have been through A LOT of hair straighteners in my life and none have compared to my Chi. I love this thing. I have had it for 5 years and it has never failed me. I have fine-textured curly hair that is prone to static and frizz (especially while living in the PNW) and this straighter is a life saver. I don't know that I can ever change brands! I'm hooked!
