Best plug if you are traveling to France or Europe
Style: Type C/G/A-Most Countries-3FT
If you ever need a European plug, this is the one to get. I took it with me to France for a whole month and it was a life saver. I was able to plug all my electronics and also have no issues with the conversion of watts. Now that I have it I take it with me anytime I travel to Europe.

Great Buy
Style: Type C/G/A-Most Countries-3FT
Bought for trip to Italy. The long cord worked great as I had several things to charge and the side tables weren't big enough. This reached the floor and nothing was falling off tables. The plug fit snugly in the socket which was key as they tend to be loose there. Don't take your own hair dryer or curling iron, they burn out from the amperage there.

Fantastic adapter for international travel
Style: Type C/G/A-Most Countries-3FT
This adapter worked as intended when needing to charge devices in Europe. The adapter was easy to attach to the plug and the cord length came in handy for sockets that were in hard to reach locations. The only thing is it does take up some space in luggage, so make sure to account for that. Would definitely recommend for international travel.
