They Work!
These are great!  Don’t trust half of these bad reviews because I can guarantee they did not do it right (lol half the tutorials on YouTube are wrong too).  I watched some tutorials, did it when my hair was almost dry, and they came out beautifully my first time.  Granted they aren’t the most comfortable to sleep in, but what do you expect...they’re great for what they are.
