Just for the battery endurance on the toothbrush alone this is a great buy! Lost my charger for 3 week when we moved, but it had power the whole time. My old Oral B would die after about 4 days of no charging! I've had this toothbrush almost a year or so now, and I have no complaints on it. The waterpick is a little intense even on the softer modes, so I just put that up, but the toothbrush, + the extra replacement heads is easily worth the $50/$60 when compared to "name brand" brushes in the same price-point. Hope that helps!
