The shark speed style high velocity dryer is just amazing. To fully dry my hair with my old blow dryer is would take almost 30 minutes and at least 15 for my daughters. I was able to blow dry my daughters hair COMPLETELY dry in under 3 minutes. I was shocked by how powerful it was. It is a bit hard to get used to how to hold and maneuver it when you’re trying to use the styling brush, but each time I try I get better at it.
