My 1st one installed on the 26th of December 2014 also. How ever my current streak was short as my streak was lost due to 2 reasons. 1st one was in 2015 I moved it and when I connected back up it gave me a new MAC ID due to it adding my login name to the MAC. Then last year I lost it when I was on the road somehow my power brick fell out of my power strip (which is vertical) so I lost 4 days,. Had we feeder IDs way back in 2015, Id have longer streak.
But I don’t do this for streaks.
