Greek sockets only work if they have very thin plugs. For example, the charger fit, but the hairdryer did not. Also, the output plugs got stuck at some point and couldn't be removed at all, they were too heavy to stay in a socket without an indentation. And after 5 minutes, it started to smell like burnt plastic. It didn't help us at all. Money wasted for the trip I took. Luckily, I had a simple adapter with me and did my job.

Attention because the adapter is not fully universal. It fits Greek, American, English, and Australian wall sockets but only accepts plugs of devices that are American, English, Australian, and USB-A (NOT Greek/European). I called the (Greek) company that manufactures it to ask why it is not compatible with Greek/European devices and they refused to answer me. Basically, if you have Greek/European devices and want to travel abroad, this adapter will NOT work for you. If you have devices with any other plug EXCEPT Greek/European, then it will serve you.

Quite heavy as construction resulting in not being able to hold in sockets. It made frequent interruptions and we couldn't charge. Even in vertical sockets, however, it did not make good contact. We got it for nothing.

I have tried various adapters over time but this one is the best. Relatively small in size, lightweight, without "hanging" on the socket and with 2 USB ports for simultaneous charging of 2 devices.

Bad product. Its weight is so big that it does not fit in the socket and it falls off. It was impossible to use it and unfortunately, another device had to be purchased. The application was made for plug type I (Argentina, Australia, China, New Zealand, etc). Three were purchased by different individuals and they all had the same poor fit. I do not recommend it for purchase.

The best universal charger by far from the others. It attaches well so it doesn't come off (not too tight, not too loose, just right, no matter how hard you press it down). It supports chargers from all countries and continents EUROPE AMERICA AUSTRALIA UNITED STATES, etc. (over 150 countries). Additionally, it provides 2 USB ports so you can charge your phone with just a cable (here I have to say that it simply does its job, don't expect something amazing, it charges slowly, compared to the original charger you have with higher wattage).

In conclusion, for the cost of the above 4-5 euros, I believe that its quality is worth it compared to some questionable value adapters that cost 2 to 5 euros. You get it and you have peace of mind as it also has the protocol of a modern safety socket.

Convenient adapter, I didn't have any issues using it. Its construction could be of better quality
