good upgrade over the oral b if you need the features [SEP] we have owned different oral b power toothbrushes over the years with the latest being the i have no complaints with the it workswhen determining if one should purchase the or the one needs to look at the additional features the providesif you have sensitive gums then you will need to purchase the there is a gentle mode additionally i would not recommend purchasing the floss action heads if you have sensitive gumswhile there is an in handle display in the it is not a digital display it is a light next to the feature you are currently selectingi do not see any difference when using the polishing mode in the however i do not have stains to determine if the feature worksthe one annoyance for me with the is that i accidentally change the mode instead of turning off the brush from time to time because the button are close enough to do thiswhile i recommend the oral b i would suggest using the if you do not have sensitive or stained teeth
