Melt your scalp hot!! Two speeds, low is higher than I'd like but not a huge deal. However, the heat is way too hot!! If you have fine hair or thin hair you can not for second hold this dryer still which is counterproductive when using a diffuser as a lot of moving causes frizz! The diffuser, while small for traveling is sooo small as to be useless! It's the size or smaller than the bottom of a travel coffee mug! Like 3 hairs can fit in their for diffusing! You can only use it from the side of your hair I suppose and not from the bottom as the scrunching upwards just makes the hairs fall off the diffuser and the blow is too powerful as to blow it around. I LOVE my Xtava Black Orchid diffuser that I use on a Revlon dryer at home but it is huge and not suitable for travel. I will stick with the silicone collapsible diffuser for travel and perhaps invest in a small travel dryer w/ more appropriate heat and a cool shot button. Save your money!
This is the most adorable travel size hair dryer I could have ever asked for. It's also very professionally packaged. And for being so small, I'm surprised at how powerful it is. Very impressed and in love.
