Excellent
Color: White/grey-Type L
Perfect size for several devices. Minimal packing space . Worked great for 1 month in Italy. I’m throwing my old ones out.

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!

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!
