Surprisingly good
The sock diffuser is well made and doesn't cause any static when I'm hover diffusing. I've got an old faithful babyliss hairdryer that hasn't given up the ghost yet, but doesn't have diffuser attachments available. Buying this sock diffuser has extended the life of my old hairdryer, and as it's a universal fit, I can pack it to take travelling with me. It's mainly for use hover diffusing as there's no firm "bowl" or prongs for pixie diffusing, but it doesn't cause static or frizz on my wavy hair so I'm very happy with it. Far less wasteful plastic going to landfill too!
