My wife loves it.
I actually bought a Chi first and then I saw this, I let her choose which to keep and she said the Chi seemed outdated in comparison.
Better heat control with an it thermometer test and she is able to straighten as well as curl easily with this iron.
For reference she has long thick straight hair to begin with but this product gave it a shine and softness like pure silk. I noticed the difference immediately from the old Remington she was using.
