Great!  Data point on battery life...
Not too much that I can add that the other reviewers haven't already said - the scale works great.  We use it for two people daily, and we use it a LONG way away from the WIFI access point - it seems to have better wireless reception than many other devices in our house.<br /><br />The reason I am writing this review is because I just had to change the batteries for the first time on the scale.  It uses 4 AA batteries, and using the scale for two people the batteries lasted 4 months and 13 days.  There are some vacations & missed days in there, but that is for TWO people too - so the rated 6 month battery life stated by Fitbit is probably accurate for one person.  These are the crappy free batteries that they provide as well.<br /><br />That's it - hopefully the battery life info is useful to somebody.  I am more than happy with that battery life - 4 months is a long time!
