It does what it says it does.
I've only used it once but it does what it says.  I have wavy to curly hair when I let it air dry, I ran a regular brush through it quick to pull out the bigger knots(bedhead) & then used the Apalus.  I did not section my hair or take any other prep...just started running it through my hair and in a few minutes my hair was straight. I'll still have to play with it and see if I can get any styling effects like feathering.
