Very soft and gentle brushing Duch the soft bristles in the interstices really good work-only is the battery performance in my opinion something short lived as I tgl.2xputzen after 1Week noticed that the vibrations are not as strong as for Anfang.Mittlerweile putz I again only with manual energy and then go again to electrically and the effect is perfect nachezu-bare and smooth teeth-really strong I buy definitely
