Bests & Worsts Reviews from Amazon

So far it seems just as good as my old Sonicare, which finally died after some years. Pro tip: The charger leeches electricity 24/7 while it's plugged in. But the batteries can last for days - and NiCds are happiest when they are drained before recharging. So don't leave the charger plugged in with the toothbrush on the charger. Unplug the charger and use it as a brush holder - use the brush and let the batteries drain - after several days it will still work, but the light will flash. Then plug the charger in and let it recharge overnight. Draining the battery fully means the unit will last years! Unplugging the charger saves you some watts. Win-win.
