I’d seen this one OEM’ed as various brands recently. A similar Japanese device years I’d purchased years ago finally went AWOL so I picked one up during my copious hanging-around time in Heathrow.
I’ve got to say, this is a terrific little gadget. My previous adapter, which was basically an plastic-coated, spring-loaded wire pick — very ominous-looking — used to spark threateningly whenever I jammed into a socket.
This little adapter is a nicely self-contained collection of prongs that fit perfectly into whatever outlet is available. No more fear of electrical fires. This cost me about 25 pounds I believe.
Highly recommended, though difficult to find online. I see you can pick one up from UK Amazon and a variety of smaller online shops.
