I've tried to USA plug and the British in Kuwait. Both have passed without any problems immediately. What does not come at the figures over is how big the part is assembled. If you know in advance which type of connector you need can be the other course at home, but the part is still loose 10 cm long. So from wall to the end of the adapter 10 cm straight. That's really hard. For a world tour, the set is therefore my opinion not suitable, because you then yes requires multiple plug. Since I find the compact version of Skross more pleasant. Although the costs even more sharply but which can be very pleasant "pushed together" for the trip and takes in spite of multifunctionality not half as much space as the adapter here with a single plugging it.
