Not sure if dual voltage feature works as claimed.

This is compact and handy, and does a decent job drying hair. It gets only three stars because,, after I switched it to the 220 voltage option, and used it outside the US, it worked for about 5 minutes, and abruptly stopped. I have not been able to get it to work since then, at either the 110 or 220 voltage, on any setting.
