It looks like it has good

I used the Swiss Type J adapter for 9 days in Switzerland. It fit into every outlet I encountered, and worked each and every time. It looks like it has good, sturdy construction. I also like that it has three prongs, so that you can get a grounded connection if needed.The only reason to drop down to 4 stars is that the **** with the USB outlets is built on the wrong side of the adapter. This had two effects. First, when I'd plug into a standard outlet, the USB slots were on the bottom of the adapter. This made it slightly finicky to connect a USB plug. It worked fine, it just would have been easier if the USB slots ended up on top. The second effect was in the Swiss three in one outlets. The bulge with the USB slots on the adaptor end up in the middle and block you from plugging anything into the other two outlets. Again, not a deal breaker, but would have been nicer if the thick part of the adapter were on the other side.


It works as described.

We used this on a recent tour; having multiple outlets was nice to have. Two devices were charged at the same time with the available USB ports. It was convenient to be able to charge multiple devices at the same time.


No Lose Pins

Bought 2. Checked the pins as some reviewers said that they came lose in the wall. Both were very tight.


Fits plugs in Switzerland

it's physically big which was bulky in the luggage and added on the block for the phone charger.
