this review title is: how do people sleep in these and the content is: the product is easy to use however i have no idea how people sleep in these you d have to be a complete back sleeper that doesn t even lean their head to the side for it to be comfortable i am going to keep them and try for daytime use on the weekend for example put on in the morning and wear throughout the day for a night time event for me i d prefer just using a good heat protectant and a curling iron to get the same effect i do know people that love these so it is worth a try i just have no idea how they can sleep with them in also i think the kind with the flat top might be easier to put in and wear having the large round part rolling around when you wrap your hair around is kind of annoyingedit i tried spritzing my dry hair a couple times and applying it wearing for an hour and blow drying carefully with low heat and air flow and my hair was still damp in some spots so it didn t hold a curl so plan on making sure you it hair is barely damp and wearing for a long time for it to be dry enough to take out.there are other information for this review, one is this reviewer did purchase it and the other is 2 people think this review is helpful.
