This is a long shot but has anyone used SCP hair straighteners in the US? I have just bought some to use on a trip to the US as the company assured me that they could be used worldwide. Just received them and the voltage says 200-240V which I take to mean they can't be used in the US which is 110V. The company tell me now that even though they are not dual voltage people report that they have used them successfully in the US. Should I send them back? Can anyone recommend some decent dual voltage straighteners? Help - don't need bad hair when I am out there!
