In use I particularly liked brushing. Reciprocation allows ideally clean between my clenched teeth, that the rotatable brush failed to do. Brushing is softer. The first brush had visible effects, note my teeth are always maintained and followed by my dentist. The higher rate is a plus, the pressure gauge is not a gimmick because it provides a good indication to preserve tooth enamel. It is highly visible, including by reflection in the mirror.
The Smart Guide is a pleasure, I love this smiley me smile every time I watch it. The Smart Guide provides the information and time zones. Important for me, it tells the time.
Regarding recharging, as with all BDE I recommend disconnecting after charging. Two advantages to this: better operating cycle for the battery and a power saving because even charged, the BDE has low power consumption.
Note: the charger is common to my old BDE same reference. The brushes are mounted on the other Oral-B models, although the rate is lower, the result is excellent.
Advantages: Brushing quality, autonomy, accessories, different brushing modes, Smart Guide, easy programming.
In less: average ergonomics with one button for all functions, but noise bearable, hardly audible beep areas of change but I prefer.
