I've owned probably more than 20 hair dryers in my lifetime and used hundreds of different hotel ones when traveling. 

A consistent theme with all hair dryers is that it drys hair! However, the different factors include how long it takes, how loud it is, and how malleable your hair is during and after drying.

This is where the InfinitiPRO comes into play. It blow dries my hair extremely AND leaves my hair surprisingly smooth and glowing. My hair doesn't feel like the dry damage sensation that other blow dryers give.
Also, the variety of attachments help style my hair as I go, which makes it so much more convenient to dry and style all in one step.

I couldn't be happier with set the bar for many years to come.
