My Teeth Have Never Felt So Clean — It’s Like a Car Wash for Your Mouth
This toothbrush?? A POWER TOOL. The first time I used it, my mouth was like, “Wow okay, we’re doing professional-level cleaning at home now.” First Impressions Lightweight, sleek, simple — not one of those overly complicated toothbrushes with 47 modes you’ll never use. Just one button. One mission. Make your teeth SHINE. Using It The vibration?? STRONG. Like “I didn’t know my teeth could feel THIS clean” strong. My gums were like: “Ma’am… what is this level of attention??” After the first brush: • My teeth felt smooth • My breath felt fresher • My mouth felt like it had a college degree It has a built-in timer so you stop rushing and actually brush for the dentist-recommended two minutes instead of your usual 17 seconds. Why It SLAPS • Cleans between teeth like it’s trying to expose secrets • Removes plaque like it owes you money • Still gentle on gums • Quiet enough that I don’t sound like I’m starting a lawn mower at 7AM And the vibration pattern is chef’s kiss. It pauses every 30 seconds to tell you to move to the next quadrant — which is helpful because I absolutely forget how time works. Pros • SUPER clean feeling • Easy to charge • Lightweight • Great battery life • Doesn’t have unnecessary features • Dentist-level clean at home Cons • The first time you use it, your brain might rattle slightly (you adjust fast) • It will absolutely expose how badly you used to brush Final Verdict If you want clean, smooth, dentist-approved teeth without paying $150+ for a fancy model — get this. Affordable, powerful, simple, and effective. My mouth has never felt cleaner and my dentist is going to think I got my life together.

Smooth, Even Clean with Smart Features
After 14 years with my Oral‑B Pro 100, I decided to switch to the Philips Sonicare 4100 Rechargeable Electric Toothbrush (Model HX3681/24) when my old brush finally gave out. I’m glad I did—the Sonicare makes the surface of my teeth feel noticeably smoother and cleaner than my Oral‑B ever did. The sensation was a little strange at first, but I appreciate that the intensity gradually increases over time, which helped me adjust quickly. I also love the SmarTimer and QuadPacer features. Both brushes had 2‑minute timers, but Sonicare’s 30‑second intervals ensure I give equal attention to every section of my mouth. With my Oral‑B, I tended to spend more time on certain areas, so this is a big improvement. The lithium battery is another plus—I don’t have to swap it out nearly as often as I did with my old brush. Time will tell if it lasts as long as my Oral‑B did, but so far, I’m very impressed. Overall, this toothbrush is sleek, effective, and thoughtfully designed. Highly recommend!

Excellent performance, but would love more color variety!
I am so impressed with the Philips Sonicare 4100 Series. I purchased the Deep Pink and Light Pink versions, and they look great in the bathroom. The advanced sonic technology leaves my teeth feeling incredibly clean, and the pressure sensor is a great feature to ensure I’m not brushing too hard. My only wish is that this series came in a wider range of colors. It would be so helpful if there were options like lavender, purple, green, orange, or yellow so that every family member could have their own distinct color to avoid any mix-ups. Aside from the color limitation, it’s a fantastic toothbrush that I highly recommend!

Smaller size
My old sonicare that I’ve had for 10 years is getting really loud and annoying so I decided to replace it and saw a good deal on this brush. I didn’t realize that when I got it it would be smaller and not as powerful, but of course that’s the reason it costs less. I think it’s perfect as an entrée into Philips sonicare because it is a very effective brush and since I’m a smaller person, I’ll learn to adjust myself to this. It’s a very very good brush.

vs old models
as good as the old models, but with smaller brush body and smaller battery, i.e. users have to charge it more frequently. Good to bring it when you are travelling

Die Zahnreinigung funktioniert sehr gut und ist in der Handhabung einfach und angenehm. Der Akku könnte etwas länger halten.
