Worked Well
Color: White/grey-Type L
No issues. Worked fine. It’s bulky so takes up more room in the suitcase

Great for Italy!
Color: White/grey-Type L
We bought these for our trip to Italy. They kept all of our hair dryers and curlers from being overwhelmed. They were perfect for our trip.

Worked great in Italy!
Color: White/grey-Type L
Used them on our recent 7 day trip to Italy. Every hotel had the 3-prong outlet so these were perfect. Charged up all our phones, iPads, and used them to convert to 120V for other appliances. Highly recommend!

Perfect travel device for travel in Italy!
Color: White/grey-Type L
We traveled all over Italy and these worked perfectly everywhere. All the ports were helpful and reduced the number of adapters we needed. We brought a 2-prong style as well, that had larger posts and was supposed to be equally universal but it was definitely not. I would definitely recommend this to anyone and recommend you skip the 2 prong style.
The only other consideration is that when you unplug a lamp or something else to use the plug then you may want an additional way to plug the lamp back in and the additional US outlets on the side won’t help, since the lamp will the the same European 3 prong plug. That would definitely be a bulky adapter, but might be worth having one in the group.
