On the Withings Activité I was happy for long. When she was finally here, and commissioning has worked very well. On the second night, the hour hand was on two clock stand. The internal clock continues to work (alarm clock, sleep recording) When that happens the second time in a week, I sent back the clock to the exchange by Withings. The Withings Support is quite possible in the German language! The replacement watch read only not be put into operation. Even after a non Baterietausch. The offered new exchange I do not use them, but sent back the clock on Amazon and then conduct my money. Thus the one star there for Amazon for the uncomplicated processing!
