Review (3/5): Good, but not blown away
This is a good product. it actually fits my Sedu 4000i, which is a big plus. Also love that it collapses to store. I have thick curly hair (3A and 3B), and so i was excited to try this. So far i am having two issues. One, it tends to collapse to smaller size during use, esp when i get it closer to my head. Not sure that's a good thing. Two, and this may be an issue of me not using it properly, it seems to make my hair too curly! I like having the longer thicker big curls, rather than the tighter smaller and collier curls - and when i air dry, i usually have big thick curls. But with this diffuser, i end up with smaller tighter curls, which is not exactly what i want. As a result, my hair overall ends up looking another 2-3 inches shorter because the curls are tighter and smaller. So if your hair is wavy and you want more curl definition, this might be great - but for me, going from curly to almost coils/kinky is not a plus. But on the plus side, it does give me good volume at the top of my head and the crown.
