I have a bunch of European plug adapters but was headed to Italy for 16 days and wanted to be sure I wasn't stuck if for some reason I could only use the 3-prong Italian standard. I got a few different adapters, but this was the one my wife and I used almost exclusively since it handled all of our devices in one outlet. We were able to plug in our ipads and phones without taking up a ton of outlets and they all charged well. I can't recommend this adapter enough, especially since it has both the 2-prong and 3-prong option.
