Good tester with a few flaws.
Pleased with the tester except for the connecter grips. They do not appear to grip very well and the black and red cords are not long enough, in my opinion. The tester works as expected and gives the results of the battery. Due to how well it preforms, I had to replace two batteries.

★★★★★ 買って大正解！バッテリー管理が一気に「見える化」しました 。
車のバッテリー状態を詳しく知りたくて購入しましたが、本当に満足しています。 測定は数秒で終わり、電圧だけでなくSOH（健康状態）、SOC（充電状態）、CCA（始動性能）、内部抵抗まで数値で表示してくれるので、「交換が必要かどうか」を客観的に判断できるようになりました。 購入前に上位機種の「BT100」と迷いましたが、日常点検やメンテナンス用途ならBT50で十分すぎるほどの機能です。コンパクトで扱いやすく、コスパも抜群です。 操作についても、ボタンが少なくて不安になるかもしれませんが、画面に出てくる選択肢を順番に選んでいくだけなので非常に簡単です。むしろボタンが少ないのは、操作が直感的である証拠だと感じました。 日本語表示には対応していませんが全く問題ありません。表示はシンプルな英語だけで構成されており、変な翻訳よりよほど分かりやすいですし、付属マニュアルは日本語でしっかり説明されています。また、YouTubeには海外ユーザーの解説動画も複数あり、英語が苦手でも2〜3回見返せばすぐに使い方が理解できます。 クリップ部分もしっかりした造りで、しっかりとバッテリー端子を挟んでくれます。剛性も十分で安心感があり、ケーブルも適度な太さがあって頼りない印象は一切ありません。全体的にチープな感じがなく、長く使えそうな製品です。 この価格でこれだけ詳細な診断ができ、操作も簡単、作りも安心感があるというのは本当に素晴らしいと思います。 バッテリーテスターはいろいろありますが、これはいいと思いますよ。

日本語の表示に難あり
日本語表示も可能だが表示がわかり難く使いずらい。英語表記のままで使った方がスムースに操作できる。
