Never received item !!! Add-on item missing from delivered package and not discovered after allotted notification time had expired so no recourse as far as a refund. Shop with Amazon almost exclusively and dissappointed to say the least.

Ex Output:
negative

A beautiful set of international power converters for travel. It is equipped with international adapters for different countries. I am very satisfied with this product and will buy gifts for travel friends again.

I'm giving this only one star mainly for how it was shipped! It was send in an amazon box that would've packaged all of it nicely, but instead was rolled up in another package & then put in the box! The hat has a crease right in the front that we can't get out, & leaves it looking more like Peter Pan's hat! If I had for time, I would've sent it back, but now I'm trying to use an iron to get that crease out.

Ex Output:
negative
