Not worth it.
When I first set this up I was so excited that it would sync with my phone and my computer and I would not have to write things down.  But it was much harder than the other FitBit devices to set-up.  Over time it has gotten worse.  With only one user and one network to remember it regularly forgets who I am.  And EVERY TIME you change the batteries you have to set it up from scratch.  I note as of 2019 that there are now many competitive products at one tenth the price.
