this review title is: works cannot speak to durability and the content is: instructions insufficient for the newbie had to watch internet video to get the hair to stay on but i probably could have figured it out with patience i really do not do anything with my hair normally not really sure they are an improvement over regular curlers with sleeves though first use had trouble getting curls close to the scalp but was able to achieve a wave in just a couple of hours of wear from dry hair fine straight caucasian hair although it did not hold up to being brushed when you leave them in overnight or to dry from wet they really do the job slight chemical odor from the foam expect that will go away not sure how long they last especially if you choose to use heat with them but for the price i think they are good.there are other information for this review, one is this reviewer did purchase it and the other is 3 people think this review is helpful.
