Very reliable and accurate scale! The Syncronisation via Bluetooth and / or Wi-Fi works great, the scale is great processed and looks good. Only the 'weather function' (shows while measuring weather information to which it refers via W-Lan) delivers basically false information. But let's be honest, nobody even needs. The Withings app and Withings profile in my opinion currently the best on the market. Motivated really constantly to respect me on my values. The measured values can be exported to Excel for example all.
*** Update ***: The unit adjusts regularly overnight and has to be reset manually each morning. The scale was replaced without hesitation by Withings However, the new balance has exactly the same problem. very annoying. Therefore only 3/5 stars
