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

سهلة الاستخدام ، قوية وفعالة ، خفيفة.

The toothbrush cleans well when it works, but after some months it suddenly stopped charging. No charging light, no vibration, completely dead. I tried different adapters and sockets but nothing worked. Very disappointing for a product from Philips. I also noticed many users reporting similar charging and sudden failure issues online. Would not recommend this model for long-term reliability.

Good quality tooth brush for the money. Had a another Philips sonicare and broke twice within the year of purchase, but this hasn’t had any issues yet. Battery could last a little longer but a charger on hand. The 2 settings I find enough. Recommended purchase.

Good

After 2 months not charging anymore. A waste of money. Bought on Amazon but not possible to change it under warranty.

Used by family

The toothbrush does not charge. And I can not return it. What a waste of money. Dont buy from this seller.

I used it for exactly 30 days , charged twice , suddenly now it's not working even after charging last night . No battery light and no change after plugging charger again ! ..

Will update when it fails.

1000% my favorite toothbrush I’ve ever purchased. The battery life is outstanding I think I’ve charged it twice ever. It does a great job of cleaning and the thing stands up to some beating in my luggage while traveling. Plus it’s pink so that’s a plus!

The price of the 4100 bounces around everywhere all the time from £35 upwards so if you can get it for around that price, it represents good value for an electric toothbrush. This is my second one, and they do the job. Simple to use (one press at the start for normal vibration or two presses at the start for a bit more vibration) and then a two minute timer starts, with a vibration every 30 seconds until it stops. Brushes last about 3 months but aren't outrageously expensive - I just bought a load to last a few years. Excellent delivery and packaging as usual.

Simply the best, as advertised! Although it takes over 16 hours to charge to full, one charge last over 3 weeks, using the toothbrush twice a day. It’s been several months now since I purchased it, the results have been the same. And my teeth feel a lot cleaner compared to regular toothbrush. I use mostly the lower speed. Very happy with the purchase!

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.
