Review title is Can't be beat for the price [SEP] My hair dryer didn't come with a diffuser and I didn't want to spend a ton of money on something that wouldn't be used often. This diffuser is decent quality for the money spent. It fit well onto my dryer, but didn't have much room to spare. I really had to jam it on, but once in place it didn't budge. I feel that it diffused well enough for what I needed, but I wasn't super impressed with the performance. If I were going to be diffusing on a regular basis, I would spring for a much nicer product. For something that will just be used once in a while, I'm fine with not getting the best results possible.
