Review (4/5): Overall, it's a great purchase. I would recommend it.
Nice product. Love the digital read out. Only complaint, neither cap is large enough for my head. Conditioning cap was way too small, but no worries there. I have plastic caps I can use instead. However, the heat cap does not come down far enough on the back of my head. I have a slightly larger than normal head, so I'm still trying to find ways of compensating.
