I was searching for Withings in the comments, and this is the only occurence. I also played with various fitness and smartwatches, but the only one I really like and stick with is Withings Steel HR.
Battery lasts a month, it's water resistant, shows me notifications, tracks steps and sleep and looks good at the same time! Also costs less than a "real" smartwatch. What a bargain to me. If only it had NFC payments it would be perfect.
So yeah, I'm with others below, I'm looking at everything else. Just bought a Withings on a whim, and I'm really happy with it so far. May spring for the ECG model once it passes FDA approval.
