Hi, Sorry I haven't used a Bossom beauty, I'm using Brava. And I can tell you, that smartbox is still working after almost 90 days of intensive wear. Everage time each day is 15 hours (mostly on weekdays is 12 hours and weekends/work-from-home/sickday is 20 hours). So it is 1350 hours on 2 set of AAA bateries.
