Query: piece of junk

This adapter is a piece of junk. I took it to Italy and it worked twice and then quit working. I tried different outlets...everything, and no luck. Fortunately I always take a back up adapter but with all the devices that need charging having only one is a hassle. If I could rate this 0 stars I would. Save your money and don't take a chance on this worthless device.
