Philips Sonicare 4100 Rechargeable Electric Toothbrush, with Pressure Sensor, 2 Intensity Settings, SmarTimer and QuadPacer, 14-Day Battery Life, Black, Model HX3681/24

Dateline: A Bathroom Sink, Under the Unforgiving Glare of the Vanity Lights. For years, the act of brushing your teeth has been a sleepy, half-conscious affair. A dull, buzzing ritual performed on autopilot before you either face the horrors of the day or collapse into bed. You thought you knew what an electric toothbrush felt like. You were wrong. You were living a lie.I am here to tell you about the Philips Sonicare 4100. And I am here to tell you that it is a different beast entirely.It sits in your hand with a comfortable, substantial heft—a proper tool, not some flimsy, skinny wand. The handle is sturdy, the build quality immaculate. It feels like a serious instrument for a serious job. I applied the paste, brought the brush to my teeth with the casual indifference born of long habit, and thumbed the power button.And was immediately jolted awake by a profound, high-frequency thrum.This was not the gentle back-and-forth of a lesser brush. This was a jump scare. A sudden, powerful hum that felt like I was holding a swarm of microscopic, hyper-caffeinated jackhammers against my teeth. This is the "sonic" part of the name, a technology that vibrates with a speed and intensity that is both shocking and deeply, profoundly effective. You can feel the difference. It's a sensation of being deep-cleaned, of having years of coffee stains and bad decisions power-washed into oblivion.There are smart features, of course. A pressure sensor that gently chides you if you're pressing too hard, a built-in coach to keep you from savaging your own gums. A timer that dutifully guides you through the quadrants of your mouth. The included cap for the brush head is a simple, welcome touch of practical genius.But we must address the one, single, baffling decision that holds this marvel back from pure, unadulterated perfection: the charger. In a world that has finally, blessedly, begun to standardize around the glorious, universal USB-C port, Philips has chosen to tether this futuristic cleaning wand to a proprietary, old-world charging base. It is a strange, frustrating relic, a small annoyance that requires its own dedicated spot on your counter, unable to join the happy family of your other modern chargers.Even so, that one grievance is a whisper in the face of the roaring, high-frequency hurricane of cleaning power this toothbrush provides. The Sonicare 4100 is an impressive, powerful, and brilliantly effective piece of technology. It transforms the most mundane of daily chores into a high-performance event. A five-star champion that will leave your mouth feeling cleaner than you ever thought possible.

This is a great toothbrush and has really improved oral hygiene since I got my first one a few years ago. I had the black one before the same series. This is newer and it’s a tad quieter than before and feels a bit lighter. I think it’s cute it comes in pink. I saw a lot of people saying their toothbrush died after 2-3 years. It says that’s the estimated amount of time for the brush to work. I had mine for 3 before it finally just gave up. If you’re brushing every single day, 2-3 times a day for 2 years that’s a lot of use. As long as you don’t drop it or bang it on stuff then it won’t quit on ya any sooner than it says. I like it and will continue to use it as my teeth feel so much cleaner than if I used a regular toothbrush again.

Phillips is a great product. It's soft bristles does a great job. The size of the brush I thought was a bit small at first, but it does a better job getting in between the teeth. It has a timer built in it, it goes off in 2 minutes, push the button and it comes back on. It has 2 speeds for cleaning and it alerts you when your brushing alittle to hard. The size as a whole is just right. It really does a good job. I would recommend.

The Philips toothbrushes are great regarding getting one’s teeth clean. However, I’ve owned three in the past 10 years and the third one has an issue where it’s constantly engaging/disengaging the charger so it makes the “boop, boop” sound constantly. The second one stopped charging after a year or so. The first one was the high-end model which cost over $100. It lasted several years, but then stopped working. Philips designs and manufacturers some great products, unfortunately this one falls flat in manufacturing.

Love this Sonicare. We have use the original for so many years we don’t think of anything else. This model works well and easier to keep clean!

I got this to replace a much more expensive Sonicare brush that went wonky on me. Crazy thing started turning on by itself. First time it happened was in the middle of the night. The noise woke me up and I couldn't figure out what is was. It then turned off. I walked into the bathroom and the crazy thing turned and started bouncing around. It scared the bejeezus out of me and had me trying to remember the number for Ghostbusters.Once I figured out it wasn't possessed and wasn't going to go back to working correctly I ordered this toothbrush. I'm not going to lie, the fact it was pink played a huge part. I knew I wanted another Sonicare so easy choice. The brush comes with a charger that plugs into a USB instead of the wall which is the DUMBEST idea ever. In order to actually use your toothbrush charger you have to buy a separate adapter. Just an absolutely TERRIBLE idea. Whoever thought that up and whoever approved it should be fired immediately.I contacted the company and asked if the charger for my previous toothbrush would work and they said "yes, no problem". So, I pop it on the charger and it does show it's charging and it does charge. Sort of. The old toothbrush would fully charge overnight and show a full charge in the morning. The new toothbrush said it's still charging three days later. When I take it off the charger it shows partially charged. Put it back on and a couple days later it shows "charging" while on the charger but "charged" when you take it off. All this is indicated by little lights and their color and flash or solid light. Basically it's just a crapshoot. I've started using it until it says it needs a charge then putting it on the charger overnight and using it until it says it needs charging. Wash, rinse, repeat.The toothbrush has some basic features that the instructions say you can turn on/off by pressing the buttons. Another crapshoot. The only thing I got to work was the high/low brush vibration feature. The rest I gave up on. You don't need them anyway.So the charger (if you can call it that) is stupid because you can't plug it into a wall without buying an adapter. The programming is a mess. The bright pink color looks more like a piece of chewed up bubblegum that's been stuck to a dirty city sidewalk for 4 years, not the pink you see in the pictures. I'm super happy they offered pink but it's the worst pink you can imagine, dirty chewed bubblegum pink. Yuk.There is a LOT to dislike about this toothbrush but.....when it comes to brushing your teeth, it works EXTREMELY well so it's a win I guess. Had this thing cost more than it did, I wouldn't be able to recommend it but all the bad stuff aside it's great for cleaning your teeth which is all that really matters. You're going to have to buy an adapter to plug it into your wall so go ahead and order one if you choose one of these toothbrushes. Then write the company and tell them they are idiots. It is what it is.EDIT: I've dropped the review from 4 stars to two. It's almost exactly 3 years since I bought this and the "On" button has collapsed into the body of the toothbrush making it extremely difficult to turn on. It started about 6 months ago when I heard a loud pop as I pushed the on button one morning. I started looking at other reviews and sure enough there were several people experiencing the same problem and even with new brushes. Clearly something has changed at the Philips Sonicare factory because quality went from job 1 to "what's this quality control you speak of?". Now's the question, do I buy another knowing it's probably going to break, buy a weird Sonicare copy that's automatically questionable or switch back to the brand I left when I switched to Sonicare? We are pretty vested in Sonicare so I may have to get another. If it breaks I'll go full scorched earth in the review, I should be doing that anyway. A once great company but now they are just putting out absolute garbage. MehEDIT: Just like clockwork the replacement toothbrush started malfunctioning and within a week was dead. These things are designed to die within a certain time, it's called "planned obsolescence". The little rubber skirt that goes around the metal brush vibrater will allow small amounts of water in and causes rust to develop on the electronics. The rubber that covers the push button is low quality and wears through 3-4 years after first use. That allows even more moisture to get inside. Philips could easily make that skirt and button cover more durable but they want you having to replace the unit every three to four years (planned obsolescence). They know there's no competition and most people will buy another one. I'm on my third one I think, maybe fourth as of yesterday. I don't consider the Oral B to be a competitor. I've used one for a few years but it never cleaned as well as the Sonicare. One one hand I despise Sonicare for purposely building junk that has to be replaced every three years on the other hand the toothbrush works better than anything else (when it does work). So I've been knocking stars off each time I have to replace one of these expensive disposable toothbrushes and we're down to two stars which means I have to go to one star. Sonicare, you make a great toothbrush but your quality is terrible and it's clearly on purpose so you get one star now. I wish I could drop another but one is as low as I'm allowed to go on here.
