Poor designed brush.
Firstly the good things about the brush, it is very tactile and has a good battery life, at least when new. Only time will tell in the long run. Now the not so good things. There are no visual indications of charge status, the only time you know it needs charging is when it stops. Similarly there is no indication when it is fully charged so over charging could be a problem. Then there is the silly idea of 3 speeds, if you want a slow speed brush then but a kids one. You therefore have to press the button 3 times to get the full speed. At least you only need to press the button once to switch it off. My old Oral B brush had a red charge light a green charging light and a big red LED to show excessive pressure. The new brush is definitely a step back in design.
