Query: Still didn't fit!

Even with all the attachments, this diffuser did not fit my Conair hair dryer. I could barely squeeze on the largest fitting, but it would continually pop off while I was drying my hair and eventually cracked down the side from being shoved on too many times. I was very disappointed and ended up having to buy a new hair dryer that came with its own diffuser attachment. I am sure the product would be fine with the right hair dryer.
