EasyClean (HX6511/50)

I can't speak to the 6100 specifically, but I got the HX6530 over 5 years ago now, and I have been more than happy with it. Heads are easy to replace, the charge has never been a problem once, and I have noticed any significant difference in the motor over time either. Presuming other Sonicare brushes have similar quality control, and can at least confirm that if you're happy with it at the start, it will likely last while keeping functionality.

We started using ours in 2011. Still going on the original motor and battery. I had to replace the seal around the motor shaft where it protrudes through the top of the body because the original had a design flaw and it tore after 4 years or so, but that’s been it. I have a spare rechargeable battery on standby just in case, but I’ve never charged it since I bought it ten years ago, so I doubt it would even take a charge at this point. Not upset that I’ve never needed to install it though. That toothbrush is a beast!

The newer ones perform as well but don’t seem to last nearly as long. Clean the old one, it’s not difficult. Then make a point of taking the head off after post-use rinse so both pieces can dry separately. That’s important.

A basic rechargeable sonic care or oral b. The more expensive versions have more bells and whistles but the basic models have the timer and they work the same in terms of cleaning. That information came directly from the sales rep that comes to our office. Either brand is fine that’s just personal preference.

Get the $40 model. It’s enough.

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.
