r/AskUKAre expensive/high end electric toothbrushes worth the money? Or just a gimmick?
4 months ago

I had my previous Philips toothbrush for 12 years until it broke down. It was at that time the most expensive model they had. Then I bought the prestige version and it broke down within a year. Now I'm using the 5300. Cheap and does the job. Can't tell the difference between the posh one and this £50 version. Philips quality has deteriorated so get the cheap one

Well, firstly, you can buy toothrush covers to put over the head of your brush which I use anyway and secondly I have a Philips Sonicare Power Electric Toothbrush 9900 mainly because of the USB charging case which works pretty well.

r/TravelHacksFrequent traveler here, how to find a practical electric toothbrush?

The Sonicare prestige or even the 9000 model has a travel case that can charge

r/onebagElectric toothbrush when onebag traveling, is that worth the space?
7 days ago

I looked specifically for one with a travel case, but those are usually the higher end (Sonicare 9900 and the like). I tried a cheap one from Concept but it cleaned noticeably worse than my Sonicare. Then last year I snatched a new Sonicare for 50 euros at a clearance sale and I'm very happy with it. This one has a built in USB A cable to charge.

r/UsbCHardwareIt's 2025. Where the f*** is the premium electric toothbrush with proper USB-C charging?

It doesn’t meet your criteria because it uses a travel case to charge via USB-C but the Sonicare DiamondClean is amazing. I actually prefer the wireless charger at home (easier than plugging in a cable and the toothbrush itself is fully sealed) but the travel case is perfect. It’s small and has a spec compliant USB-C port. It also looks fairly nice. The only downside is that it’s very expensive.

I’ve got the top of the range Phillips Sonicare 9900 and the one beneath it 9000 which is actually more powerful. Never use any of the apps or Bluetooth but happy with both of them. It feels like you’ve been the hygienist first few times you use it. Really good at getting round the back and removing nicotine stains.

r/BuyItForLifeIs it worth paying more for the high-end Sonicares, or are the basic ones just as effective?

I've used Sonicare for at least two decades. My first brush was E-series lasted me for like 15 years and the only reason why I upgraded it is because I fell in love with the look of DiamondClean series. That first E-series brush was actually still going strong when I got rid of it. DiamondClean was the best because unlike the cheaper models it didn't have any nukes and crannies for gunk to collect it, especially on the bottom because there was no hole for the charger. It looked amazing, but after 7 years the button finally stopped working - it's not sealed and while I always rinse and wipe down the brush after use eventually there was enough build-up to stop working. When I went ahead to look for replacements I was horrified at the price points. I will never get another diamond clean again because now I know the button is a weak point and no matter how much of a clean freak you are, eventually it will get all clogged up. So, for that ultra clean design and minimalist appeal Prestige is really the only option for me. But I just cannot bring myself to cough up that kind of coin. And I know I'll never use any of the smart features. It may be a darn good toothbrush, but it's still a toothbrush, and I want to use it like a toothbrush. I bought 4300 series, low budget model which only has one cleaning mode. I hate that it has all the nooks and crannies for the residue to collect, but it's cheap enough where I really don't care if I have to dispose of it. Build quality is definitely NOT there. I'll be surprised if it lasts me for more than two years. But cleaning experience is the same as DiamondClean,, which I kept just on clean mode and never used any of the smart features. I do miss how easy it was to keep clean that brush though. Can't win.

r/DentalHygieneelectric toothbrushes: sonicare versus oral b?
about 1 month ago

Hello, dental hygienist here! I have both ( Oral-B iO series 6 and Sonicare Prestige) and in my day-to-day life I prefer Oral-B iO, mainly because od the small brush head and generally feeling after brushing my teeth. For traveling I opt for the Sonicare, but just because it has more convenient travel case which can be plugged and charged. If I would have to choose I would go for Oral-B.
