We're heading to the UK on Saturday. My wife purchased this adapter so that she and my daughter can use their Ipod chargers, hair dryers, curling irons etc in the UK.

I don't think it will work. It converts plugs but according to the instructions it does nothing to the voltage as far as I can tell. Inputs/outputs are the same as the standard voltage in the country. Since the UK uses 240 volts, I don't think we should be plugging 110 volt electrical devices into the system. What does everyone else think?
I'm surprised the adapter has no comments or warnings about this. Or, am I missing something?
