I have been using Sonicare brushes for decades. The cheapest Sonicare will give you as good dental health if you follow instructions as the most expensive model with WiFi and a bunch of other useless crap. And I mean useless.

I bought a pair of the top of the line ones with all the bells and whistles a couple of years ago from a big Costco sale (half price, still $125 for two), downloaded and installed the app, and on day two the app alerted me that it was time to change the brush. On day two of using it. I deleted the app and also ignore the weird "change your brush" noises it makes and the LED it flashes on the handle. I can look at the brush and see when I need to change it.

Next time, I will buy the lowest possible cost one. Like this one.

Our community has rated this post as helpful. If you agree, why not thank FrugalCrusade

What sucks is how the new 4100s don't have the same power as the old 4100s. I know because I got another 4100, and the power sucks. Obviously a way to spend less on producing the brush.

Great find and incredible timing, thank you. Just had a dental visit yesterday, and electric toothbrushes came up. I asked the dental hygienist what she recommended at a reasonable price and she recommended the Sonicare over Oral-B specifically. Said the $30 ones are perfectly good - you can spend more for extra features but you just don't really need them. They said the Sonicare uses pulses over the oral-b that spins as the performance difference.

4100 is better than 2100 model.
And still has been downgraded. The toothbrush now vibrates the heads so badly that they end up enlarging the hole. They end up falling off the brush long before they wear out.

My old one just got really loud. It lasted less than 2 years. I guess they have a 2 year warranty, so I got a new one from them. That's when I discovered the new ones have less power.

I am disappointed because the model below it, that has the screw on brush heads was only about 20 dollars, was 5 or 6 years old, and still worked. That wasn't going to make them any money, though.

Just FYI, the free toothbrush head that comes with the promo/warranty register inside the box is not valid anymore. They just give you a 20% off coupon code.

Bought two 4100s about 5 years ago. Wife's is still going strong, whereas mine died recently. (Battery was clearly degraded for the past year or so, and even early on it felt like my battery didn't last as long as it should, so I might have gotten a slight dud from the start.)
Going for this 2100 as a replacement. Seems all I'm missing is the pressure sensor (which I'm not sure I got any benefit from on the 4100 anyway). Only trepidation is that it seems all of the Sonicares at this point aren't as sturdy as they used to be.

Good time to replace mine from 8 years ago. Still runs to this day, but have to charge it damn near every couple days.

I really wish you could swap out the batteries instead of having to buy a whole new one.

These are awesome though. Def feel a difference with this vs traditional toothbrush. Also I suspect my dentist is happy I use this as teeth in much better shape.

I just wish the replacement heads weren't so expensive. I tried the generic and they seemed to work okay. but I just splurge on the heads at Costco when they are on sale. If there is one thing that one can spend $ on, it's taking care of your teeth.

USB charger is a bit odd. Most of us have a spare phone charger that can be used, I suppose.

Just my opinion, but I switched from Sonicare to Braun because the refills are cheaper, and I like the rotary motion. Generic Sonicare refills are hit or miss, with most being miss

You're suppose to replace the heads often

I have a 10 year old one with the screw ons that still works as well as the day I got it. Still holds a charge for over a week. Was tempted to get a newer one but after reading yours and some other comments perhaps I should continue to use it til it eventually does die.

Yep. E Series rocks. You can still get generic heads on Amazon. Heck, you can still get a generic compatible handle on Amazon.
