These are the best straightners I've tried! I wasn't sure what to call them as it just says 'babyliss' with 'Type C31b'...anyway, they are really good, I like them 10 times more than my GHDs! They heat up to around 230 degrees, have a velvety material above the ceramic plates so it doesn't get too hot for your fingers, swivel cord, worldwide voltage, affordable (got mine on sale in Sainsbury's for £12.99 but they're normall under £20 I think)...I have relaxed hair but it's still pretty wavey and curly at the roots where my regrowth is. This straightner leaves my hair feeling soft, silky and shiny unlike most others I've used. Heats up within 60seconds and doesn't damage my hair near as much as my GHDs did. Great purchase.
