Bought for $130 From their website - The Glider professional hairstyling flat iron features ionic ceramic tourmaline-coated plates that use 8 HeatBalance® microsensors (4 on each plate) to regulate the temperature and evenly distribute heat so that fewer passes are needed through your precious hair. That’s the best way to get silky results that shine while protecting your hair cuticles from overheat exposure. Plus, the plates heat up in seconds so you don’t have to lose any time while adjusting the temperature setting via the dial between 140-450°F to suit your particular hair type and texture. The flat iron’s floating plates have curved edges that provide extra flexibility to straighten, curl or flip your hair. Auto turns off if you forget to shut it off! HSI offers a lifetime warranty
