I ordered the curlers because I wanted big waves / curls with volume at the base. Within 30min hairstyle coincides. No more volume and no wave let alone Locke. I feel it is because the curlers are not really hot. I have more than 10 years a classic Heizlockenwicklerset (with the three standard sizes) of Tschibo and so I have absolutely no problems. The curler from the device are however much hotter. This one of Remington are highest can be warm ... burn you with those things before not :) Another negative point is that you do not know when the curlers are done heated. There is no measuring uncle. I thought that I might not let heat up long enough. Did you but let heat already 1h before I turned it into the hair and again the same game. Some are so enthusiastic. Perhaps my hair are simply not for the curler. I have long straight hair.
