Did not work
It appears there is a known issue with this product, it will give an error code &#34;err&#34; when it is &#34;thinking&#34; to display your weight.  I searched all over Fitbit's support forums and site.  There is no reference to this issue, however a quick search on your favorite search engine shows many people are experiencing this same issue.  I have since returned this product.  Good concept, poor manufacturing.
