Nice product, but poor packaging from Amazon,
レビュー対象商品: 日章工業 トランスフォーマNDFシリーズ(電圧ダウン)120V→100V1500W NDF-1500U (ホーム&キッチン)
I bought this to use with my rice cooker and bread machine (home bakery) in the U.S. It is made in Japan and looks very well made. The size is compact for a 1500 W transformer. When I plug it in, the output does read 100V, which is awesome.
I am, however, taking off one star not because of the product itself, but because of the flimsy packaging. It is a small yet (very) heavy object, but Amazon shipped it out in a very thin box with minimal padding and no warning sign on the outside. When I received it, there was a big hole on the box with post office tape over it to keep the content inside. And it looked like the transformer had previously fallen out of the packaging and got dented in both front and back. Luckily the transformer still works, but I was very disappointed by Amazon's lousy packaging.
