Index S2 Smart Scale - Black

Mike M

worth the money (and it's affordable)

costs a bit more than the entry level withings scale we tried (purchased elsewhere), but oh my goodness, setup was sooo much easier, and the display is worlds better. the app is the icing on the cake, no up selling for extra subs, just "here's your data" and done. stumbled across Sierra by chance, and was impressed with their process from start to finish.
