Good overseas, don't use it in the USA as the plug doesn't lock.

Liked the ability to plug into the EU plug in Brazil using our US chargers. Went to a hotel and ran into an unusual situation. The outlet was US but the laptop charger we needed to plug in was the EU plug. The US prongs on the charger extend but do not lock. Never was able to get a charge. Had to get an adaptor from the hotel. Also, don't let your wife plug in her hair dryer, it blew the fuse. Just like the warning labels tell you. I gave it 2 stars because it worked as designed but failed to lock the US plug in place.
