works great until the charger burns out [SEP] i have now owned two different oral b rechargeable toothbrushes with the same charging base the first one stopped charging after about months and this one which i only ordered because it was black friday and the price was and i thought a higher quality version from oral b would have a better charging base burned out after less than months i keep the charger away from all water sources and thoroughly dry the toothbrush handle before putting it back on the charger the base is a cheap piece of plastic and i will not risk ordering this brand againamazon customer service was great i missed the return window by one day and because the item was defective they allowed me to return it for a refund i do not know what toothbrush i will try next but i will order it from amazon again
