With over 2,000 pieces of feedback and a near perfect rating I would say this is a good hair straightener.
Right now on Amazon  you can get the HSI The Styler Ceramic Tourmaline Ionic Flat Iron Hair Straightener, 1 inch  for $38.85 shipped.
After years of struggling with bad straightener my hairdresser looked at me and said “I know you are cheap but you need a GOOD ceramic straightener if you want it to work.” I dropped $80 on a straightener and it turned out she was right.
Since this one is originally around $199.99 this is a really good deal.
As always be sure to double check the price before buy- Amazon  prices change quickly!
