I have a dual voltage
Babyliss mini hair dryer that I bring when I absolutely need one. However I mainly use this for drying rather than actual styling. I have thick absorbent hair that just loves to hold on to moisture and smells so drying is more of a concern than actual styling.
My recent stays at IHG, Residence Inns and Courtyards have been OK for decent working hairdryers. Every now and again, in older properties, there are some wimpy dryers.
Thanks for mentioning--this looks like an interesting choice as it looks really small.
