Amazon have just reduced their Wet 2 Straight straighteners from around £54. (Please note these are not the slim version). They retail around £75-£80 elsewhere although the slim version is cheaper.
Straighten hair from wet or dry, 5 year guarantee
Temperature lock, digital display 150C - 230C
Ceramic coating with micro conditioners for smooth hair all day
Super slim and extra long easy glide plates
15 second heat-up, worldwide voltage, heat proof pouch
I have no knowledge of straighteners but am looking for some for my daughter if anyone can give me any recommendations.
