Such a great idea! This is basically a straightener that can lock together and be a curling iron also. All you do is clamp it together and move a switch which locks or unlocks it.
When it's in curling iron form, the barrel is the perfect size for full, wavy curls. It's not going to give you any tight little curls. When it's in straightener mode, it's a small, but effective straightening iron. It's definately not the most state-of-the-art in either category, but it gets the job done, and is certainly as good as most single-use devices on the market.
You can adjust the heat setting between 1 and 25, and there is an option to blow air while straightening, which is a great time-saver.
Overall, this product is great if you want to be efficient and/or don't have a lot of space to store tons of seperate hair tools.
