How does this hairbrush do what it says?

The GentleStyle Brush features a patented design to massage your scalp, evenly distribute products, detangle without stress, diffuse with any hair dryer, and style hair. Innovative vents provide even heat distribution and airflow control. A unique finger shape design creates extra body and lifts the hair root. Wide spaces between bristles detangle your hair without pulling, while the ergonomic handle is easy to grip and comfortable to use.
