I've used the non-USB model for several years. It is small & neat, and easy to slot together for packing or storage. The colors make it simple to find which one you need. Has never failed me yet. I just bought the 'USB' model and expect same reliability. Unless it's changed, the country list & required plug are on the box, so keep that box. Office very helpful as well.

I loved it so much I bought more for Christmas presents for family.
Comparing Universal Travel Adapter + UBS with other multi adapter, this is more convenient to travel, It doesn't add much weight to the adapter itself (after plugging into the power source) as other adapter will become loose and not properly receive power source.
These converters are very simple to use and they are incredibly useful while traveling overseas. The colors make it very simple to determine which one to use. I would highly recommend these converters to anyone travelling internationally.
Bought this for my daughter who travels internationally 3 - 4 times per year. She was thrilled with it. She just left on a trip where she will use three different power sources. fesources
This was a well received gift.
