HX9368/35 (Sonicare Diamond Clean), purchased 2018. 2020 I was concerned about the seal flaws, so I purchased a new designed seal from eBay, a UK seller. Fitted it. Haven't had any issues. I open it yearly to inspect internals for any corrosion. 2025(December) the "white" LED is dimmer than the others. But I've never used the other modes honestly, only ever used the "Clean" mode. I never kept it on constant charge, only when the battery indicator shows amber, then I place on charge.
I had one of the old diamondclean models and it stopped working so i ordered a new diamondclean model from philips which was useless - i ended up buying the older model from aliexpress and it worked perfectly
I had an old diamond clean that just died now after almost 13 years, it was the one from costco that included a UV cleaner. The toothbrushes are much more expensive now, i think im going to try a 5100 due to their price on amazon.
My sonic care finally died after 8+years of use shared with my wife. So heavy usage.
Replaced with a two pack from Costco. 1 died in about 3 months. SonicCare replaced it with an upgraded version and so far it’s been ok. The other one is fine but stays in our travel bag.
