Query: Compact world power adapter

This collection of adapters snaps together in a very compact way and provided all I needed in my recent trip to Italy and Greece. One thing many people aren't aware of is that most electronic gadgets are designed for world markets work with 110v or 220v so all you need is the right plug instead of a voltage converter or transformer. This kit has a collection of those plugs. Love the way they all snap together to save space and stay organized. Recomended!
