However, users should be careful with the tempered glass surface, especially around the edges, to avoid damage.

The scale requires 3 AAA batteries, which are included, and it has an auto shut-off feature to conserve battery life. On the downside, the scale relies on Bluetooth for connectivity, which might be a bit limiting compared to Wi-Fi-enabled scales.

One helpful feature is Baby Mode, which lets you track weight changes for babies and pets. The LED display is backlit and clear, although most detailed info is best viewed in the app.
