Philips Sonicare 7900 Much prefer it to the Oral B it replaced, got it for half the normal price in black Friday sales
I have a Philips Sonicare 7900, got it with a significant discount online, it’s excellent. Battery lasts weeks. Had a previous version years ago which was great too and just wore it out. In between I got an oral-b on a dentist’s recommendation which I stopped using after a month, terrible battery and needed loads of cleaning below the brush head because of a hollow casing, whereas the Philips needs a lot less attention.
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.
I have travel size Philips Sonicare with built in usbc charging. No cavities in 5+ years.
Every sonicard that I've bought has broken down within 2 years. They are good but definitely not BIFL.
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 bought a sonicare from Amazon for cheap and it lasted about a year. I bought another sonicare from my dentist and it's still going strong, six years later.
I have tried manual toothbrush and the Philips One travel toothbrush and they don’t compare to the full size Sonicare, which I now bring on every trip. Obviously, I don’t bring the big case.
I take off the head and use the cap that comes with head refills https://preview.redd.it/55qc75oeonog1.jpeg?width=778&format=pjpg&auto=webp&s=1c0dc3805041a35b7bb85842c5837ee331d11a83
Why do you need a case at all? I travel with a Sonicare and separate the head from the body and use the tiny cap that comes with replacement heads. https://preview.redd.it/scm4aoprhmog1.jpeg?width=778&format=pjpg&auto=webp&s=e5fddee74590ffed76e7b348a37da8497592a7f9
I have a different model, but you can buy small alternatives to the case charger.
