THESE UNITS ARE VERY GOOD!I have contacted the manufacturer. Their answers are vague 'we haven't tested' - 'we can't guarantee' blah blah but SOME of the Dlan Wifi boxes have 100 - 240v and some only 230v.
I see these are offered on some US websites US $ but shipped from UK or Europe. I hope someone will have tried them on 110v and can say "Yes they work" or "No - they don't"
