I just got this device and finished installation which took me more than half an hour. It cannot recognize my wifi for more than 10 times. I had to abort the installation and start again. and then the device cannot be connected to the app until my fourth try. I almost gave it up and decided to return it. After all my efforts on installation, it only told me my weight and BMI and failed to tell me the rest which I care more about. I will come back to add more after several days, especially on the rest functions. if it still doesn't work, I might just return it.
I just hope on the scales in the morning and hop off. No need to open the app! No need to have the phone even in the same room! The Scales connect to WiFi and therefore send my results "to the cloud". I get to work and open my phone app and it's all there. Amazing. As a bonus, it shows me the weather when I get on the scales, which is actually quite useful. I know what to expect, what to pack for the rest of the day. Brilliant.
The scale would only provide weight. The other parameters only worked rarely and then not at all. Had multiple correspondence with Withings to try to resolve the issues. Had to return the product for a refund.
