Works like a charm!
I am so glad I found this. I had purchased a lotus diffuser but it didn’t fit on my deva curl hair dryer.  (I was actually looking to purchase a new hair dryer when I found this.) I wasn’t sure if it would work but it works perfectly. It is a rubbery material and each end is a different size...both ends actually fit on my dryer. The first way I put it on it did not fit with the diffuser, so I turned it the other way and it worked. Yay! I highly recommend this product.
