I just repaired electric toothbrush. Again, for the third time (with different toothbrushes in my family, fuck Philips).
After two years of usage rubber button lost sealing. So replace it with screw furniture cap and seal ot with thermal-shrink tube (40/20 mm). Using only home hairdryer.




i buy replacement heads online, and i brought off-brand sonic there too. phillips is just op for any sonic toothbrush, thats why i dint it buy it. the secondary brand, is aquasonic, i i think are still kind pricey. oral -b is fine if you just buy the 1000-1500, and get the replacement heads online.
the ones i bought from (that are imported from germany) seems to last longer than the one in states(the heads)
