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.

Cute little fountain. My bird bath is entirely in the shade and it squirts up 8". If you put it in your bird bath, it will empty it in 30 minutes. Great entertainment.

Everyone was correct when they said this item stinks. It immediately began to lose its charge. Even when I was not using a plug in headphone, it was dying within 15 minutes. I then submitted for a refund or replacement after Amazon claimed they were fixing these products. Now they have canceled my replacement and will not let me return for a refund since it is past due.
