AFTER RETURNING ONE ORDER ( DID NOT HOLD CHARGE ) THIS "REPLACEMENT HAS WORKED WELL SO FAR. HOPE THE BATTERY RECHARGE LAST LONGER THAN THE ORIGINAL ONE I HAD WHICH DIED AFTER ONLY 2 YEARS OF USE.
I bought this a month ago on the recommendation of my dentist. I'm glad I did. I like the timer on the toothbrush especially when brushing in the mornings.
