Huge Upgrade From a Manual Toothbrush
This toothbrush works great and leaves my teeth feeling super clean every time. It’s gentle on my gums, easy to use, and the battery lasts a long time. I’ve definitely noticed a difference since switching from a regular toothbrush. Great quality and well worth it.

This is a well made toothbrush.
I've been using $20-ish cheap knock-off sonic toothbrush. It's been working, but I got curious how Philips or Oral-B products are - they are definitely more expensive, and I've seen many good reviews on them. So here I tried this 4100 today for the first time. Definitely feeling the difference - garden hose vs fire hydrant. Brush head will be smaller then your expectation. This means you need to get busy brushing your entire teeth, but again the brush can reach to the deep area in your mouth = good for through cleaning. There are two levels of power you can control with a button. I am using the highest settings, works good. Timer feature is an added bonus.

⭐️⭐️⭐️⭐️⭐️ Life-Changing Toothbrush — Deep Clean, Gentle on Gums, Keeps My Mouth Fresh! I’ve been using this Philips Sonicare 4100 Electric Toothbrush for months now, and honestly, it’s one of the best purchases I’ve made for my daily routine. This isn’t just another toothbrush — it’s like having a dentist-level clean in the comfort of my own bathroom!  From the very first brush, I noticed an incredible difference. My teeth feel dramatically cleaner than with any manual toothbrush I’ve used before — it literally gets into the nooks and hard-to-reach spaces between teeth and along the gumline that I always used to miss. That deep-clean feeling stays all day, and I even notice that my mouth feels fresher longer after brushing.  What I Love Most: 🦷 Powerful Sonic Cleaning Technology – This brush uses high-frequency sonic vibrations (up to tens of thousands of strokes per minute). It lifts and breaks up plaque far better than a regular brush ever has, and I can actually feel the difference.  💆♂️ Pressure Sensor Protects My Gums – I tend to brush too hard (guilty!), but this brush gently reminds me when I’m pressing down too much with a subtle vibration indicator. My gums have never felt sore or irritated, even on sensitive mornings.  ⏱ Smart Timer & QuadPacer – It automatically times your full 2-minute brushing session and paces you so you spend the right amount of time in each section of your mouth. Gone are the days of rushing or guessing if I brushed “enough.”  ✨ Two Intensity Settings – You can choose between gentle and stronger cleaning. I usually stick with the higher setting because it feels powerful without being hurtful, but it’s great to have options, especially if you’re new to electric brushes.  🔋 Long Battery Life – I charge it and then forget about it for days. The battery easily lasts through more than a week of twice-daily use, so no constant charging hassle. Some users even get much more than the advertised battery life.  Gentle Yet Effective: One of the things that sold me on this model is how gentle it feels on my teeth and gums. It cleans deeply, but it never hurts — no scraping or painful pressure. Even after a long day, brushing with this leaves my mouth feeling clean and refreshed without any discomfort.  A Few Things to Know: • There’s only one brushing mode with two intensity levels — so no fancy app or multiple cleaning modes like some higher-end brushes. That said, for everyday oral care, it’s perfectly sufficient and does the job exceptionally well.  • Some people note replacement brush heads are a bit pricier than some competitor brands, but with the BrushSync reminder, you’ll always know when it’s time to swap them.  Final Thoughts: If you want a toothbrush that cleans thoroughly, protects your gums, keeps your mouth fresh, and never hurts, this is absolutely worth it. It’s far superior to any manual brush, very user-friendly, and a great value for what you get. My dentist has even commented on how clean my teeth look at check-ups — and that’s coming from someone who used to dread going! Would definitely recommend this to everyone looking to upgrade their brush — especially if you want something gentle, effective, and easy to use every day. ⭐⭐⭐⭐⭐ — I love this toothbrush and will continue using it daily!

Good quality brush, but charge does not last as long as older model
It's working fine and does the job, but I do agree this model is smaller and the rechargeable battery does not last as long as my older model.

My Teeth Feel Like They’ve Been Polished by a Tiny, Enthusiastic Pit Crew
I used to brush my teeth like a common laborer, moving my hand back and forth like I was trying to start a fire with two sticks. Then I bought the Philips Sonicare 4100. I realized within thirty seconds that I had been doing it wrong for thirty years. My mouth doesn't just feel clean; it feels like it’s been through a high-end car wash and then buffed with a microfiber cloth. Why Your Mouth Needs This Sonic Engine: The Vibrations of Victory: 62,000 brush movements per minute. If I tried to do that manually, my arm would fly off and hit the mirror. This thing creates a "microbubble" situation that reaches into crevices I didn't even know I possessed. The "Stop Pressing So Hard" Sensor: Apparently, I used to brush my teeth with the same intensity I use to scrub a cast-iron skillet. The 4100 has a pressure sensor that pulses when I’m being too aggressive. It’s like a gentle life coach for my gums. The Two-Minute Timer: I used to think two minutes was a long time. It turns out, my "manual" two minutes was actually about forty seconds. This brush keeps me honest. It’s the longest two minutes of my life, but my dentist’s inevitable praise will be worth it. Battery Life for Days: I charged this thing once, and I’m pretty sure it’s going to outlast my current lease. It’s the Energizer Bunny of dental hygiene. The Life Impact I combined this with my 1,000 RESHLIX Floss Picks, and I’m fairly certain my mouth is now the cleanest environment on the North American continent. I went to the dentist last week and he asked me if I’d recently had a professional cleaning. I just smiled—a blinding, sonic-powered smile—and walked out. Pros: My teeth are so smooth I can’t stop sliding my tongue over them. It’s slim, it’s sleek, and it makes my bathroom look like a futuristic spa. Cons: The vibration is so powerful that if you turn it on before it’s in your mouth, you will decorate your bathroom mirror with toothpaste art. You’ve been warned.

Nunca había usado uno y escuchaba que eran muy buenos y que valían la pena. Por los dientes sensibles no opté por los que giran, me fui por este que vibra y pensé que quizá sería algo Meh! … Lejos de la realidad. Es un súper cepillo! Se siente MUY POTENTE en velocidad baja hasta puedes llegar a sentir tus dientes en peligro jaja pero no te causa daño, al contrario, con los manuales me estaba lastimando el esmalte y sobre todo había partes que se sentían difíciles de alcanzar. Este lo conseguí en oferta, solo viene un cabezal y es pequeño, alcanza lugares difíciles y se siente suave con las encías, definitivamente lo recomiendo para dientes sensibles. Hay muchas opciones de cabezales para diferentes propósitos. Solo 2 velocidades y muy sencillo de usar. Lo volvería a comprar sin dudarlo.
