Philips is so CHEAP !  This company sells the 2-brush set with only one - count it, one - recharging base.  So your family member with whom you share the bathroom has to remember to remove your brush from the stand and put their brush, each day, or  some such arrangement.  How Stupid, how lazy, how cheap!  Philips writes in the manual that comes with this thing that one should not use the recharging base from an other model with this unit.  I had another, older unit.  Of course the new brush was purposely made not to fit the old recharger -- planned obsolescence.  But I got it to fit by expanding the base.  I heated it with a hot air dryer and pushed the somewhat softened plastic of the bas outward to make room for the slightly larger base of the new brush.  That, plus a bit of scraping.  Teach Philips a lesson and buy another brand!
