Great product, but only uses older Wi-Fi protocol
Operation of this product is excellent.  It puts your weight directly into your Fitbit account.  Setup is also quite easy.  It does a good job of discriminating between users.  The only reason I do not give it 5 stars is that the Wi-Fi does not support 802.11n mode.  My home network was set up originally to only operate in 802.11n mode only, and the scale would not connect.  Once I changed the Wi-Fi network to operate in b/g/n mode it connected properly and has worked fine since.  It is really not a big deal but can be frustrating if you don't have the router set up correctly for the scale.
