DiamondClean Smart 9400 (HX9917/89, HX9918/89, etc.)

Not sure which route you’ve went, I’ve had 3 9400’s , one 7400 and currently I have the cheap one, I hate it , it’s not near as powerful, they don’t last long in general, but a good toothbrush feels so much better, I recommend spending the money and don’t expect it to last long, I’m lucky to get a year out of one

I really wonder how you can break them that much. Me and the wife are using a 9400 for years without any issues.

My two Philips Sonicare DiamondClean Smart 9400 for German market are made in China. Also we have a chinese made Sonicare 5100

Which one? I had the diamond clean 9100? It only lasted 4 years 😭

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.
