✧ Product Name ・Sense-U Smart Baby Monitor 3 (with base station) ・Smart Baby Monitor (Bluetooth version) I will sell them as a set. Suitable for twins. Purchased new in March 2025. ✧ Product Description You can monitor two babies simultaneously with the smartphone app. It monitors breathing (movement), sleeping position (prone position), and body temperature, and it's convenient because you can finely adjust the sensitivity of the alerts. The set contents are as shown in the photos, and all accessories are included, so you can use them immediately upon arrival. (I haven't checked the battery level, so if there is no battery, please use a spare button battery) ✧ Condition The base station was always running for temperature and humidity management, but the sensor units were used less than 10 times each. There are no noticeable stains on the products, and they have been disinfected. ⟡ Notes This is a used item. Please refrain from purchasing if you are looking for a perfect, like-new condition. Since this is for babies, it might be best to disinfect it yourself before use for peace of mind. Instant purchase without comment is OK ◎
