Review (5/5): Elegant appearance, thoughtful design
This was actually the 3rd straightener of this type that I bought, but the only one that I kept. I love the "Lock" feature, and the fact that the buttons are in the main part of the handle, where even without a "Lock" button, I wouldn't be accidentally turning it up or down every time I pick it up.
It works very well on my wavy hair, giving me fairly straight hair when I'm too lazy to blow dry. It's much quicker on air-dried hair than my flat iron, although I'll follow up with the flat iron if I want to look a bit more polished.
I would definitely recommend this product.
