very useful

Used these for a trip to Iceland and worked with no problems. They are a tad bulky but on the flip side feel pretty solid. They don't convert VOLTAGE--they just adapt the plug. But most electronics these days already support anywhere from 110-220 V. We don't own anything that would require a voltage converter. It's very handy that each adapter accepts two devices at once.

Bought these before a trip to Iceland, and they work as advertised. Plugs are the correct size for the type C receptacles used in Iceland and other European countries. Has two receptacles for American plugs, one 3-prong and one 2-prong, the 2-prong receptacle is polarized. Handy to be able to connect two devices with American plugs. As indicated in the product info, these adapters *do not* perform voltage conversion! If you plug the adapter into a 240V outlet, 240V will appear at the adapter's two receptacles. To avoid damaging devices you want to plug into the adapter, make sure the device can handle 240V. Power supplies for many devices support a range of voltages 100V-240V. Devices supporting 100V-240V will work well with these adapters. Devices that only support 120V (and not 240V) will likely get damaged.

Worked great for charging phone, computer and camera batteries and

This 3 pack of plugs came in handy on my trip to Iceland. My family and I were able to charge our phones, tablets and laptops with these. The plus is that they have two plugs in each receptacle. Just know that these are not made to use with hairdryers or hair clippers as they are not power converters. They did their job and I am happy with my purchase.

Worked great, even though it constantly makes a chirping/squeaking sound when plugged in. Used this all over Europe, and it worked just as if I was in the United States--has 4 USB ports, and 3 outlets, so I could charge 7 devices. But, whether I had 1 device plugged in or 5 devices, this would chirp the entire time it was plugged in. It is also a bit heavy. If you could get past the chirping, this is a very useful thing to have when traveling internationally.

Bought a three pack of adapters since I was heading to work in Italy for six weeks. They work for not only three pronged plugs, but also have ANOTHER outlet (for two prongs) on the side. This was ridiculously handy for my hotel, where there was only one outlet and I needed to charge both my phone and computer while using them. The value for these is incredible. (It is only for US to Italy.)

Took these to Finland and they worked there very well.
