Product review (3 stars): not for super coarse hair but possibly good contender for everyone else
I personally have EXTREMELY coarse hair.. so on that note.. not for me.
This personally just is a frustrating tool that doesn't help me at all. However my mother has much thinner hair that is super curly and I think she will get good use out of it. I do think for the right person it can be very helpful. But with a lot of hair not so much.

Also if you press one of the twirling buttons at a wrong time or too long it can be kind of painful and yank your hair. Be careful.
