Review: As described by seller. Product was quality built and versatile as it can crimp several styles of connectors. I would recommend
Review: アマゾンのレビューはいつも半信半疑ですが、価格も高くはないので購入してみました。結果、今までXHやデュポンコネクタは中国駐在時に購入した工具で圧着していて失敗が多かったのですが、この工具にしたら圧倒的に失敗が減りました。ダイスの作りも以下まで使っていた工具よりだいぶ良さそうに見えます。少なくともホビー用途なら（わたくしはホビーユーザーです）十分に満足できると思います。
