I've been using just a regular, cheap hairdryer for ages and received the Con Air one complimentary from BzzAgent in exchange for my honest review. I have curly hair and have never used a diffuser. Let me start by saying, "Wow." My curls were gorgeous and I had no frizz what so ever. Not sure how that works, but normally my hair takes forever to dry abs this cut the time in half. It has many setting and even a cool setting to set hair styles. It's also very powerful. This blow dryer is very much worth the price for what you get and better than other brands at the same tier.
