Ive noticed that in 5 hours there is a Prime deal for the Nokia (Withings) body + scales.
I urge you to look at the Health app reviews first if you are thinking of buying them.
I have owned these scales for over a year. They were great but when Nokia took over Withings and updated the app they no longer work with the app and are now no more than a basic scale.
When the app updated I instantly lost connection and havent been able to connect since.
Nokia are not replying to any complaints of which there are many on the app site.
A shame as they WERE good but I wouldnt want anyone to waist their money on a company that cant be bothered to deal with a major issue like this.
