Am completely disappointed

I bought the Withing Pulse Activity Tracker to me recently and find this really great - unfortunately he has his difficulties with the automatic synchronization - and exactly this difficulty sometimes runs through this machine. When setting up the evening the transmission worked, the morning after that. For manual entry, I can stay with my old scales and this error has been increasingly criticized - not fixed. Still disappointed I was when I noticed that this "expensive" device simply displays the fat mass; my jetztige balance displays also muscle and water content, and that would be at this price, in my view because minimum performance what I would expect. On the whole, a great pity for the great idea - unfortunately the technical implementation still needs to be better.
