I purchased this great product from CHI and I am so glad I did. I was worried about the price, however using my points, I was able to snag a great deal. I'm very pleased that this product provides a hair dryer, curling wand and DETRACABLE roller brush in one product. My hair is very frizzy and medium length. Having used other "roller brush dryers" I know the difficulty in trying NOT to get your hair in a tangled mess while styling! I love that I can retract the firm bristles on the wand with a twist of the heat protector knob at the end of the wand. Believe me I have panicked while using this product, getting my hair all rolled up and thinking I can't unwind it quickly. I immediately turn off the dryer, turn the detractor knob, and Presto - your hair is free.The tourmaline feature greatly reduces frizz. I noticed I used less heat protection products in my hair while using this product. I very much like the interchangeable nozzle attachment to dry my roots and scalp first, then switch out the attachment to the bristle wand. I've practiced for a month now and am getting better accustomed to the feel and weight (not heavier than an average blow dryer), of this dryer. This product is very well made. The attachments hold strong with the help of magnets and are not flimsy in the least. There are three levels of heat intensity which I like, however, it is a little difficult using the button to power up/down between settings. The only other slight negative is when powering from hi - med - lo, the air level does not decrease, nor Is there a button to adjust the level of air. This would not be a negative feature for me. I'm very pleased with the product.
