Sonicare 2100: Szybkość Do 31 tys. ruchów szczotkujących na minutę (nazwałem to obrotami, bo chodzi o cykle pracy silnika magnetycznego) Sonicare 4300: Ruchy soniczne \[ruchów/min\]: 62 000 (też tak to nazywają).

Same. My dentist recommended it, I bought the black one because it matched a lot of my decor. I’ve had it more than five years and it’s going strong

I used Sonicare during Invisalign. The slim head was great for cleaning around attachments and buttons.

Philips sonicare. Using the base brush since 5 years already. Amazon had replacement heads for cheap. Usually stock up during Thanksgiving.

You don't need the diamond clean. Just the basic sonicare (we've gotten these on sale at Costco, 2 of them with chargers for around $100. The diamond clean connects to an app to "coach" you and can probably send use info to your dentist. The basic sonicare we have still has a 2 minute timer to let you know when you're done as well as vibrates every 30 seconds to let you know to move toa different section of your mouth, and a light to let you know when the head needs changed (although I've found you can tell that just bya decrease in power). That said, right now the DiamindClean is on sale at Costco, 2 of them with chargers and travel cases for $179

Been using a basic Sonicare for like 4 years now and it's been solid. The battery thing is legit - still goes forever between charges. I tried the Oral-B at my dentist's office and it felt way more aggressive, almost like it was gonna strip my enamel off lol For what you want I'd just get the cheapest Sonicare model, the expensive ones mostly add timers and pressure sensors that you honestly don't need

I switched to an oral b one when my sonicare died. I like it better. I also got the basic one after having the sonicare with all the bells and whistles. I prefer the basic one. Also, you can get generic replacement brushes for much cheaper than the brand name ones.

Mine broke before two years and I went back to my old one that was the basic Sonic. The earlier ones last way longer.
