## Customer Reviews

### ⭐⭐⭐⭐⭐ 温湿度計としてとても良い
*by き***き on September 16, 2025*

バックライトはないが、温度や湿度の状況が文字も大きく見やすい。さらに外でもSwitchBotアプリから部屋の温湿度を確認できるので便利。

### ⭐⭐⭐⭐ 精度も良く、遠隔で確認できるのが良い
*by A***ー on August 20, 2025*

2台購入して使っているが、CO2、温度、湿度ともバラツキが小さく、精度は許容範囲と言える。アプリで計測データが確認できるので、とても役に立つ。もう少し安価なら有り難いが、これも許容範囲か。

### ⭐⭐⭐⭐⭐ 期待通り
*by ト***ロ on September 9, 2025*

期待通りの商品でした。外出先からも部屋の温度、湿度の確認も出来てます。
