Expert Review Summary

Our clinical assessment and verdict for each device

Eufy Smart Scale P3

Recommended

"A feature-rich smart scale with an excellent display and competitive accuracy for under $70."

Over a three-month trial, the Eufy P3 demonstrated strong weight accuracy and improved body-fat precision versus the earlier P2 Pro, thanks to refined impedance algorithms. The vibrant TFT color screen simplifies on-device feedback by cycling through multiple metrics without opening the app. Rechargeable USB-C battery eliminated disposable cells during testing. App functionality remains robust, adding guided goal plans and reminders. Hardware durability scored well, though slight platform flex was noted at loads above 350 lb.

Withings Body Scan

Recommended

"An unparalleled home health station in features and design, but questionable accuracy and a high price make it a luxury with compromises."

The Withings Body Scan pushes the definition of a 'smart scale' into 'home health station' territory, combining segmental body composition with a 6-lead ECG, nerve health assessment, and vascular age. Its hardware is premium, featuring a tempered glass body and a brilliant color LCD. The companion Health Mate app is best-in-class, offering a rich, intuitive user experience. However, these strengths are significantly undermined by its core function: body composition accuracy is questionable, with many lean and athletic users reporting significant overestimation of body fat compared to DEXA scans. Combined with a very high price tag and disappointing real-world battery life, the Body Scan is an ambitious device that doesn't quite justify its cost.
