Review: とにかく充電が長持ちで､通常使用で､1週間は使えます。 私の使い方で､同期をたまにしないと､時計の時間が少しずつずれていきます。 機能は十分で､私が使いたかった､血中酸素レベルの24時間管理､歩数､ウォーキングのデータ取得等は問題無しです。 この値段でこの機能､画面の大きさは､文句無しです。
Review: 5との性能差をそこまで感じなかったため購入したがかなり良かった 個人的いい点 ・バッテリーが持つ ・GPSが使えるのでスマホがなくとも 運動データが取れる ・血中酸素濃度が測れる ・値段に対して機能が多い 悪い点 ・時々GPSを取るのに少し時間がかかる ・天気アプリの精度がそこまでよくない ・タスクの追加にわざわざアプリを使う必要がある(XiaimiやRedmiユーザーを除く) 使用した感じ、個人的にデメリットはあまり気にならないものだったためかなりコスパの良いいい商品だと思う！

今までのスマートウォッチの充電が持たなくなってきたので敬老の日に父に。 安価で機能もよしです。 毎日ウオーキングに使う程度ですが充電は2週間くらい持っている様です。
