not all it is cracked up to be [SEP] got the diffuser it fit on my bloweryayright nowhen the silicon heats up it becomes quite floppy and does not hold the diffusers cup shape so it does not hold your hair up whilst you are trying to diffuse it it was flopping all over waste of money more hassle to send back so lesson learned a hard plastic cup with a silicon ring to fit different blowers would be a better idea
