highly recommend for travel or home [SEP] so glad i bought this collapsible diffuser it flattens out well and easily slides into tiny spaces in my suitcase it is sturdy enough that it does not collapse while being used and it fits snugly around oval and round shaped hair dryer ends it is my new go to for on the road and quickly gives my wavy hair great results no more shoving a giant hair dryer plus its hard plastic diffuser into an overpacked suitcase no more having to leave stuff home or bring an extra bag less cha ching for airline fees it is my new best travel buddy highly recommend photo is of round ended hotel hair dryer
