it does a better job than brushing with regular tooth brush [SEP] although i never had good experiences with philips products and with other electric toothbrush brand like braun oral b and recently i found bucks on the ground so i do not really care if it does not last long after reading some bad reviews that water gets inside the battery compartment which i see is happening but still i am sure i will find the way around it after the years warranty expiresnow for the intended job cleaning your teeth is much better than the moving action from oral b braun the minutes limit bothered me a bit but it takes seconds to turn on again and back to the job and i do feel my teeth more slippery after using itthe included batteries lasted for weeks and the unit will not operate as powerful as with a new fresh set of batteries this thing is really powerful so do not judge the unit is power with the batteries suppliedthe handle is one of the reason i took one star off it becomes very slippery and when you need to turn around the toothbrush you need to use both hand so it does not fall from my hand unless you are not like me that i realized that i use my other hand to lean on the sink probably will not find it awkward but otherwise is not big dealif it fail i will update this review and let you know how not surprised i was
