FYI, Sonicare gimped the vibration motor on the 4100 a few years ago. If you're replacing an older 4100, you'll probably notice a difference

This uses much less battery than the iO 8 I got for $110 (with $100 Amazon card opening bonus). It's much less flashy and doesn't put a smiley on a display, but you just want it to brush your teeth, right?

My old one lasted 7 years and was still going. It was still fine but the battery was getting weak, too bad they aren't replaceable. I decided to try one of the Oral-B IO brushes because there were always people saying they were great. Big mistake and by the time I realized I hated it, it was too late to return it. Now I want to get another 4100 and when I look at the recent reviews it seems enshittification has hit hard. Can't rely on any brand or model these days😭

Agreed. This one has much weaker vibrations. Not sure if it cleans as well. Is there models where the vibration is stronger?

Pre-enshittified 4100 were "Philips Sonicare ProtectiveClean 4100 Rechargeable Electric Toothbrush" , model number HX6811/01. Look for ProtectiveClean on the box. You could still get some at Best Buy up until last year. Once in a while there'll be new ones that pop up on eBay.

I believe the better motor \ build quality start with the 5100. Philips redesigned the 4100 and secretly started selling the garbage replacement under the same name.

After I bought the 5100 my dentist told me I should have gone Oral B anyways. Given that and Philips shady redesign, I would just go Oral B next time.
