Plug Adapter, BESTEK Universal Travel Ad

I used these everyday for the whole 6 months that I was in Japan with my USA electronics and I never had any problems. I didn't need three of them but my roommate couldn't charge her laptop so I gave her the third one and she said it worked great. I can't comment on how well it works in other countries but they definitely worked in Japan. I used them at several hostels, at my University, and dorm while I was there and they weren't difficult to plug into the wall, nor were they loose. They were just a perfect fit! I truly can't find any complaints, this product saved me and my roommate and I'm so glad I thought to buy these before I left. Also, if you have anything that is a simple two-prong plug then these won't be necessary for Japan. All of my two-prong cords fit and worked really well without these adapters. Just remember that their voltage is lower over there so somethings took twice as long to fully charge as they do in the US.
