Review (5/5): This is a game changer for home and travel.
This adapter works to keep my diffuser on my blow dryer. It does a great job. It also works great on most blow dryers so it's my secret weapon along with a collapsible diffuser for ensuring I can diffuse my hair at the hotel when traveling. No more having to pack a blow dryer. Yea for more room in my carry on. Highly recommend.
