Works for what i ordered it for and is nice, super easy to attach to any hair dryer it seems. It asked about compactness when writing this, um I wouldnt say its to compact you could fit it but I would not bring it with me on a trip. I would rather just bring the dryer, but for at home its great and I love it.

I purchased this diffuser on a recommendation from a Manes by Mel YouTube video. It fits my Elchim 3900 dryer perfectly!

My hair is straight, fine, blonde and pretty flat. I spend a lot of money on volume builders and found that drying my hair with a regular blow dryer wasn't doing me any favors. I wasn't sure if this would work for me, but it surprisingly does add some lasting volume. It fits pretty much any blow dryer and pops right on and off - no tools or anything. I like to add mousse and then flip my hair upside down and use this diffuser to dry my roots. Yee haw! I have body.

It falls off and smacks me in the head when I use it. I attached it to my DevaDryer.

I got this because it was recommended by a youtuber. It's ok. Not really special? I liked the idea that you could change how much air flow comes through but it's already a diffuser so you're obviously going to have it turned up all the time lol it doesnt really fit my hot tools blow dryer which is a bummer:/ the attaching sleeve part isnt really very stretchy like I believed it would be
