Review (2/5): Hot and awkward
The up/down buttons are in a dangerous place, where your fingers are, so I kept hitting the up button and the temperature climbs fast! The entire brush is big, heavy and awkward to use.
You have to push both the up and down button at the same time to get the temp to read in fahrenheit for americans. You have to do it each time you use it too.
If you have thick, strong hair and it can handle high heat, you may like this. It does heat up quickly. I have tiny, frail thin hair so it was dangerous for me.
