Not realiable
It simply doesn't work.  Just went through flu with 4 family members.  Could not count on any of the readings.  It would show 99.0 multiple times in a row, when in reality baby had over 101.0.  I would NOT recommend it.  Going back to Dr. Brown, never had an issue over 8 years of continuos use (I guess it was it's time).
