OREI USA, Canada Adapter Plug, Europe, UK, China to US American Adaptor - Grounded - Type B - Universal Socket - EU to US - 4 Pack

I tried a lot of adapters and these are by far the best ones. Imagine you are in Australia and in your room you have a lamp plugged into an outlet, but you need the outlet to charge your laptop with your US charger... Not a problem, you install this adapter on the outlet, replug the lamp using the center socket of the adapter which is universal, and on the top of the adapter there is an extra US socket to plug your charger. Voila, you now have a charger and a lamp all working. The sockets (both of them) offer a solid physical connection with tight friction, so your charger won't fall off the socket. Really good adapters, the best ones.

I often found my so-called universal adapter with C plug did not work well for some outlets in the EU. So I now got these small E/F plugs for this situation especially for heavier-duty applications.

Great plugs! Excellent quality and very durable for the price compared to most! All plugs on it work perfectly together unlike others where plugging in more than one device makes it trip.

Type C plug adapters received have a oval shape plastic section that holds the prongs instead of a hexagonal shape plastic section as depicted in the advertising photos. This means they will not fit in some type C sockets! Be warned!Update: The company reached out and sent me replacement adapters that match the advertising photos. I am updating my rating to 4 Stars as a result of good customer service. Thanks for your help.

I brought back lamps from Europe and these are exactly what I needed to make them work.

This review is for the "OREI 2 in 1 USA to South Africa Adapter Plug (Type M)".I'm in Johannesburg now on a work trip and I just tried to remove it from the wall (for the first time since buying it). It separated in two, leaving the metal prongs still fully in the electrical socket and internal metal electrical connectors exposed in a highly dangerous manner. Fortunately the electrical socket I was using was switched - there are sockets here which are not switched and are always live. If you live in the USA, bear in mind that the 220V used here in South Africa (or indeed in Europe for equivalent adaptors) is far more dangerous than your 110/115V.The amount of force I used was so low that the metal prongs did not even move from the socket - the unit separated before that could happen. Looking at the internal construction, the only things holding the adaptor together are 3 plastic clips. These didn't even break during the separation - a light force simply defeated them. Furthermore the nature of the design is such that in the event of this happening, the live (if the switch is on) metal connectors are exposed in a way that is very easy to touch, and which makes it very difficult to remove the failed adaptor safely if it is in an "always on" socket.This purchase was a set of 2 adaptors and the other one has not failed. Having experienced the above, I feel that the design of the product is so poor that I will bin the other one and look for something more robust (prefereably held together using screws or similar). I accept that manufactured products can fail from time to time, but it is not acceptable for this to result in as dangerous situation as I experienced here.(I took various photos of the broken adaptor but the new format reviews page does not seem to allow me to add them.)
