The cleaning results are impeccable, as described here several times. From my perspective, the Pressure sensor triggers too late - because you have very strong press. Battery life: A person brushing twice a day showed 10 days. The integrated charge control can save the plug in the power supply - is also recommended in the manual. Charging took so about 15 hours - is not a disadvantage for me. The disadvantage I find that is designed only for 230 V AC adapter. We often travel to "110V countries" this is a real disadvantage. The predecessor settled with 110 V but still charging, but this should make it again and again on the charger. How is that in this model, I can not say - but I will complete. 1 star deduction for Pressure sensor and power supply.
