Finally found the best heatless curler after trying out other curlers in the market. This item gives best hair curls when used for atleast 6 hrs on hair, so I used it during sleep and found best curles as shown in the image attached to this review. Cletcher & scrunchies were top class. The materials inside it is not thermacol but light-weighted clothes cushion with rigidity. I fully bend it 180° and it still did not break or became loose. Ends are properly tucked and secured with a finishing pearl pin at both bottoms. I have thin, bra strap length hair and after overnight use, it made my hair look bouncy - voluminous and results were like 90's blowout style. Great for everyday styling with minimal hair damage. I've heard about no results or hair breakage issue from many users but it didn't happen in my case. If you have faced issue similar to it than it's bcoz you are not using this product in correct manner. Even I failed during my first attempt, but figured out the right way during my second one. For finding correct way, I advice you to watch 4-5 youtuber's video and make sure all of them are different people bcoz there is more than one correct way to use this curler on various hair length, so you can choose one out of various different ways as per your hair type , length and type of curles. Also, depending on your preference make closed-tight rolls of hair on this for heavy curles and light-spaced rolls of hair for beachy / loose waves. The only downside you may face is that you cannot sleep on one side when using it. I was only able to sleep on my back properly too. But , I did not mind it when the end results were so beautiful. Remember that in life , NO PAIN, NO GAIN. It helped me resolve my hair insecurities and gave a gorgeous look to my hair for which I have received countless compliments. I found this better than heating curlers and plastic rollers which has historically caused me hair breakage, thinning, brittle and so much damage. Right now, I'm in my hair care era to reverse all previous hair damage mistakes from heat styling and regrow my hair & this product is one of the best investments I have ever made without any hair damage ever.
