Well worth the price!  Yes, it works well!
I wondered about the reviews but this thing works.  Plugged it in and tried all three settings.  It works perfectly.  I actually found it soothing.  It heated all over as would be expected.  I will be using low or medium because my hair is a little fragile.  I thought the high heat really got very warm.  This is something I wish I'd bought a long time ago.  The cord was longer than I expected too.  The picture doesn't reflect size of cap or length of chord very well.  Both are generous in size and length.
