All and all i think the product is awesome. Warms super fast, cools fast as well. I'm nit picking but, the only thing I don't love is changing the temp and powering off. You have to double press the power and temp up button to change the settings.
This also lets you not turn it up accidentally and singe your hair so I get the reasoning behind it. Maybe there is a way to change it on the next model. Its a little finicky and I miss the 2 at the same time. But again, I am unjustly tearing this thing down. I love it and will recommend.
