The diffuser packs easily. It is not as good as a standard one but  works reasonably well for a travel solution.  The two detractions are 1) that it does not fit many dryers, particularly a number made by Conair.  I ended up having to buy a new travel dryer to go with it (Revlon makes one that fits) and 2) it collapses while being used but it works when it's not extended .  Bottom line: not perfect but a good solution for those who pack light.
