I am on my second Sonicare, first was (according to Amazon) 2016-2024 when the battery died. Reading this thread I JUST learned I could have replaced the battery, but I bought a Sonicare 9500 in 2024 and love it even more.

näin necrobump niin io sarjasta 6 on se kultainen keskitie hinnan ja ominaisuuksien näkökulmasta, saat suurimmanosan lippulaivamallin ominaisuuksista mutta ilman isoa hintaa. isoin hyöty jos hyppää 9 on että saat 3d seurannan harjaamiseen 6 vyöhykkeen sijaan.

My last sonicare lasted over 7 years, it wasn't even dead when I ugraded to the $300 version and I have no regrets, it is something you use everyday, if not twice a day if it works it is worth it to last that long, in most cases you only have to worry about the battery losing charge and that is kind of unavoidable, unless you know of a brand that lets you repalce your own battery, although after like 10 years I would probably just want a new device with advances in tech and just general wear and tear.

My Sonicare with travel case (with integrated charger) is by far the best electric toothbrush I have ever used. Came here to say this.

Not bulky, no. And the built in charger is a blessing.

I've been using Sonicare toothbrushes forever. I usually get the package of 2 of them, in case I can convince my husband to use one (unsuccessful so far) or for travel. I like the one I have now since it has more "intelligence" and lets me know when to replace the brush head.

Yup mine just broke down after 18 months (DiamondClean 9000 series) Going to order a cheaper one for replacement this time and see if it works as good
