## Description

Xiaomi Band 9 Midnight Black

Review: スマートウォッチを、試しに使ってみたい方に、オススメです。 スマートウォッチはお値段が張るものが多いてすが、手が出しやすい価格設定が嬉しい。 電池持ちも良く、ゴツくないのも良いです。 バンドも着せ替え可能なので、好みのバンドを購入し気分やファッションに合わせて変えられるのも楽しいです。
Review: 睡眠ステージのモニタリングをしたくて購入。 程よい大きさで軽いため、就寝中も気になりません。 バッテリー持ちも良く充電も速いのですが、時折、スマホとの同期が外れます。 原因によって対応の仕方が変わるので、ご自身で問題解決できない人だと使用が煩わしく感じるかもしれません。 また、購入時に本体に付属しているリストバンドは外れやすいので、オプションのバンドに交換することをお勧めします。
