My last pair of GHD finally died after 15 years, so I splashed out and bought these new Chronos ones and I am so glad I paid the extra for this model. Not only do they leave your hair super smooth after just 1-2 strokes, but they are really smooth as they run through your hair, no more burn tips if my ears either , my hair remains straight the next day too (weather permitting). I really like them, glad I spent the extra money and would highly recommend them. Originally posted on www.ghdhair.com
