Doesn't fit my dryer, but duck tape works.
You get what you pay for.<br />My hair dryer measured perfectly inside the dimensions that supposedly fits. It arrived, and will not stay on.<br />I will give this 3 stars because it does fit right inside the barrel. Not in any way would it say on by itself, but a little duck tape later and this diffuser has worked well for me so far.<br />So if you don't need to take it on and off, and you don't mind the slightly redneck appearance of a duck taped dryer this could work for you.
