Ordered the rollers in Dec. Loved them at first. Noticed that they were losing heat as time went on. Come March getting ready to go out for my Birthday, turned on the rollers, blew dry my hair, went to roll my hair and the rollers were stone cold. Power was on. tried plugging it in to a different power sorce. and nothing... Tried them a few times after that and still nothing. I guess you get what you pay for. They were only 20 something. But I know I'm going to stay away from Revlon on my next purchase.Joan in Pa
