Very useful for holidays abroad, works well with charging multiple things at the same time. Light weight for suitcases or hand luggage. One issue that sometimes arises is because of the shape and locations of plugs, sometimes it can’t fit into the socket because of its ‘T’ shape, I have found that it fits upside down in some sockets (not sure if you’re meant to do that) if there is an issue with connecting to the socket if it’s blocked by a higher desk or bedside cat in the hotel room. But it’s still a really good travel socket with multiple connectivity ports and usb sockets.
