### ⭐⭐⭐⭐ Review
*by あ***郎 on January 14, 2026*

1年半程度で本体のバッテリーか激減したため、仕方なく外部バッテリーを物色。 名前の通っている商品のほうがまだ安心だろうと購入しました。 装着感もまぁまぁで、全体的にかなり重量感は感じるけど顔側重量感は少し解消されて概ね満足。後頭部バッド無しから交換したのですが、あってもなくてもどっちでもいい感じ。 充電はこれだけすればいいので楽ですが、本体供給断のスイッチがあったらありがたかった。 支点部分はクリック等なくフリーに動き、跳ね上げた状態で止まってくれないので寝転がった時に使いにくい。 あとは締めるノブが状況によって滑るので、ちょっとギザを付けてほしい。
