I currently have some old GHDs, they work properly but the wires have become exposed in one spot on the flex therefore can’t continue using them at the moment for safety. Does anyone have experience of using GHD repair services as I’ve seen some online? They are stating around £30 for a repair. I’m not sure if it’s worth it because they are old but they work fine apart from the issue with the wire, or should I just get some new ones?
