I can report that it is quick and easy to do, does not take any skill, is not terribly uncomfortable to sleep in, and holds the curl through the day. The secret is to apply leave-in condition to my wet clean hair and dry it to 90 percent, then wrap the hair around the curling rod and go to bed. The whole process takes less than five minutes and when I wake in the morning, I have amazing curls that last all day long without adding anymore product... so this no-heat method really does work well. 

 I bought this product recently and I used it twice. Product is soft and nice, I could sleep twice with it and it did not bother me at all. It definitely gave my hair the type of curls I was expecting. Large waves and curls. I’m so glad that now, I can avoid using heat tools on my hair to get this look.The waves on my second time using it are better than the first time, so it does require a bit of practice for better results, however, it worth mentioning that it’s super easy and quick to put it on. It did not come off during the night, it stayed in place. … I definitely recommend this product! 

 I truly did not expect this to do what it claimed to do, but my hair looks fabulous!!!! … Truly is a game changer for me and takes so much time off my morning routine for getting ready….just wake up and your hair is done 

 This actually was surprisingly easy to use and produced great results! The first time using it does take a little bit of figuring out how to wrap your hair in the best way. But once you figure it out, it's pretty easy. I didn't have any issues sleeping with this and it didn't really bother me. The results looked great in the morning considering how relatively simple and easy it is to do this. I don't use it every night, but when I want my hair to look extra nice in the morning, it's an easy tool to use the night before... The quality seems pretty durable for this and the fabric is pretty good quality 

 As someone with naturally straight hair, I love curling it. However, I don't love hair damage. …This roller set is WAY more comfortable since it's one long piece instead of a bunch of small rollers. Since it's all one piece, it also takes me way less time to wrap my hair around it. …The curls that you get are not as tight as you'd get with the conair foam rollers, but they still produce a nice curl that lasts a long time. 

 I’m so happy about this! I had purchased a different style of heatless curler from a different seller that hadn’t worked for me and was uncomfortable to sleep in. I decided to try again with this one, and I’m so glad I did. …My curls weren’t perfect, but I think after I get the hang of it and try it a few ways, they’ll improve. I was just so happy it worked at all, and that it was so comfortable to sleep in.
