BESTEKEurope Travel Plug Adapter, Grounded Universal Type E/F Plug Adapter EU to US Adapter - Ultra Compact for Most of Europe, Asia Countries and More, 3 Pack

They small and capable for the intended application for the international traveler to Africa and UK.

These work great in several countries for a plug adapter to use American electric items abroad. I used it in Argentina, South Africa and Costa Rica.

I got the "world adapter" version for a trip to France (EU plug) and the UK and it worked flawlessly in both countries. These adapters are very compact compared to other adapters I've seen, which makes them much more convenient to pack.One thing to be aware of is that this is a just a plug adapter and it does NOT convert the outlet voltage. As the product description says, you need to make sure the device you plug in is compatible with the outlet voltage (ie. be careful with high power things like hair dryers). I just used the adapter to charge phones and camera batteries and didn't have issues. However, you'll find reviews on travel adapters like these causing sparks and I suspect this is often because someone plugged a device in that couldn't handle the voltage in the outlet.

This adapter is compact and convenient for international travel. It fits well into the outlets in Brazil and South Africa, and it’s easy to use. However, I wish the build quality was a bit more robust, but it does the job efficiently.

These plugs were great for our last London trip. Don't forget to take them on the trains out of London as they can be used for charging your phone or tablet while you are using the wifi.

Came in a three pack exactly what I needed

Bought these for a trip to Argentina and Chile. I did not have the necessary adaptors for those countries because my travels have always been Europe/British focused. These worked perfectly for plugging in computers and i-phones to charge. They are simply adaptors- not converters- and are good for that purpose.

Very easy to manipulate and use, especially if your trip spans across different countries with different plugs. Note that the UK plug doesn't have a ground prong, just a plastic piece that goes into the socket so if you need ground protection you may want to find another product. The way they fit the euro two prong (type c) is very helpful; it slides into a sheath in the body and is easily removed and inserted on the back when needed.
