Review (5/5): 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.
