I bought a pair a pink ghds about a year ago and they had just suddenly stopped working. The fuse hasn't blown but they just won't turn on. I had a similar problem with my last pair and am now fed up with just replacing them!!
i would e-mail the company and tell them your promblem with your straighteners and let them know that you are disscustered with the product only lasting a year especially for what you pay for them,my sister bought apair of ghd straighteners for £90.00 and after 2 years the main cable worked loose and the straighteners were going off and on so she e-mailed them and she sent them back and they sent her a new pair.The e-mail address is info@ghd-uk.co.uk
