Product review (5 stars): Outstanding styling tool.
It's become my go-to hair styling tool.  The left/right buttons turn the brush in that direction and adjust according to the heat setting.  They allow you to style with one hand. They don't work on the cool setting (as would be expected since the cool is used to set your style.) My hair is a middle length bob and it's great to be able to touch it up in the morning with this tool.  I would definitely buy it again and would and have recommended it to others.  It also does a great job straitening out bangs or adding a bit of volume to the root area.
