Comes recommended! I have the Withings Aura and Withings WS-50 Smart Body Analyzer, Black myself, and while it sounds dumb to have your alarm clock and scale connected to the internet, I’ve found it super-useful for keeping track of weight, heart rate, and sleeping pattern.
Also, it’s spiffy to be able to switch off your alarm from the crapper if you wake up before it sounds.
Gonna get myself a Withings Pulse O2 now and see if it does anything for me… http://www.withings.com/nl/blackfriday/
