I was able to plug in all my devices with one plug.
It worked great.
It also has a blue light that appears to stay on all the time when plugged in, so at night it is quite bright.
Product worked on my trip to the Seychelles.
Other adapters don't have the third, round, grounding pin but this one has and it renders it much more stable in outlets.
Now that I am back in the USA, I am informed that I can't return them either...buyer beware!
More than once have I woken up to a dead phone; apparently this stopped working in the middle of the night, and didn't charge anything.
Bought a cheaper $7 one from a nearby drugstore as this one is so temperamental; I have no idea when it will decide to actually work anymore!
Don’t buy there is no return for any reason.
We traveled in Hungary and in Austria and could not use these adapters because the shank is too short to plug in far enough to secure it.
