After just eleven years of excellent service, my Oral-B 25.526.3/”9500 Triumph” electric toothbrush died from mechanical failure – the gears went a bit toothless (oh the irony), so while vibration was still on, it wouldn’t rotate the brush. I did exchange the NiCd battery some years ago, but the drive cannot be disassembled, so that was a total loss. Meh.
At the time I spent 70€ and this model was on the higher end of the Oral-B product line. 11 years later even the cheapest models are lithium battery based and I would expect essential technology has trickled down to the base models. […]
