Ghd glide is not universal voltage so please take care if you use it abroad.
There is a high voltage version (220-240 Volts) this can be used in: EU/UK/ANZ/SA
You can use high voltage version on a low voltage supply (e.g in the US) without causing any damage to the product, but performance will drop significantly.
There is also a low voltage version (110-120V) which can be used in US/TWN ONLY
If the low voltage version is used on high voltage it will not damage the product but performance will drop significantly.
Please refer to the labels on the product if you are unsure of which voltage product you have.
