The scale itself makes a very value own impression. However, very clear dust catcher in black, you have to admit, just if you have pets. Installation and setup are very easy, has been tested with multiple iOS devices and accounts. That all went smoothly. The different accounts (father, mother, child, cat ^^) are detected and synchronized.
The results seem to be quite accurate, so far there were no big outliers in any direction. Multiple measurements in short periods appeared to confirm each other measurements.
The online features are ... well ... ok, not more, it is basically also merge only a platform to the data of different gadgets from Withings, but as I do the other bells and whistles not need, which is more restricted , The target weight function is quite nice, but as you could have done more of it.
All in all, for the balance, despite their prices strong buy recommendation.
Anecdote: Before we tried the functionality of the balance (weighing + WiFi Sync) with a Wii Fit Balance Board recreate, also works great, but unfortunately only with a manual synch as Bluetooth device :)
