Improve your brushing technique with QuadPacer and reach your recommended brushing time of 2 minutes with SmarTimer. Experience up to 14 days of regular brushing after a single charge, bringing a new level of convenience to your brushing routine (based on two periods of two-minute brushings per day on standard mode). Did you know that brush heads become less effective after three months? The replacement reminder tracks how often and how hard you brush, then reminds you to replace your brush head once it's time for a new one. ¹ vs. a manual toothbrush ² based on a study of over 2,600 dental professionals (dentists and hygienists) conducted in the United States, Canada, Japan, China, Korea, Thailand, Germany, the United Kingdom, Switzerland, France, Belgium, Austria, Italy, Spain, Sweden in 2022-2023

Review: Simple, Effective, and Exactly What He Wanted - I bought the Philips Sonicare 4100 Rechargeable Electric Toothbrush for my husband, and he really likes it. This model is simple and straightforward—just two speeds, no extra bells and whistles, nothing overly complicated. It just cleans your teeth, which is all he wanted. It's a good design. It also has a good battery life, so he’s not constantly recharging it. Overall, a great choice if you want an effective electric toothbrush without all the fancy features you’ll never use.
Review: 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.

## Questions & Answers

**Q: Why doesn't the new 4100 model have a regular plug ?  why on gods green earth did they cheap out and put a usb plug in there ??**
A: According to the review in WireCutter (Sept 2022), you can contact SonicCare and receive a free plug adapter.  I've just ordered the 4100 on Amazon.  I don't have the serial number yet, because the product doesn't arrive until tomorrow, but SonicCare customer service just told me that they would send the free plug adapter once I provide the model number and serial number to them.  They confirmed there is no charnge.  It will take 7-10 days to receive the plug adapter once I am able to provide them with the serial number.  I'll do all of that after the product arrives tomorrow.

**Q: Does anybody make a single speed electric toothbrush? I'm so tired of cycling through the speeds**
A: Cycling is the most effective way to brush each quadrant sufficiently.

**Q: What is the purpose of having two intensity modes? How do you know when you should use one or the other?**
A: if you have more sensitive teeth and gums you can use the softer mode

**Q: What do the green and yellow lights mean? what about the beeping noise after the 2 minute brush? I thought low battery but is it replacement head?**
A: Hi! When the brush head replacement reminder light of Philips Sonicare Toothbrush HX3681/24 lights up amber, kindly replace your brush head.
