Very good tooth brush strong enough smart enough too much cleaner than your own hand work you can feel the smooth and clean clearly after using it it will take 24 hours to be fully recharged a little bit slow and each time you should change the brush mode unless you use the daily mode all the time it cant remember the mode you use last time

The pause in brushing happens as planned but maybe 20 of the time there is no beep

Sonicares brushes do not come close to cleaning my teeth or getting them as white as this

The bluetooth feature of the black and more expensive one is completely pointless in my opinion

The addon functions like external timer clock is basically useless

I like how it works but instructions to set it up are very confusing

This little gadget that comes with it to notify when toothbrush needs to be charged i am ready to throw away and the tray that holds additional brushes is too big will not use this one
