4100 Rechargeable Electric Toothbrush, 1 Brush Head, Black | 700% More Plaque Removal¹, Pressure Sensor, 2 Brush Settings, 14-Day Battery, Includes Brush Head Case, BD5003AZ

Have loved these toothbrushes from day one. Charging is easy and simple Noise level is low and unintrusive. Vibrations are great and powerful. Durability is solid and long lasting.

Charge is convenient and stays charged days before needing to be recharged. I like the soft bristles and the noise level is not an issue. My teeth feel very clean after brushing. I would recommend this product and would purchase it again.

I always get annoyed with the increasing costs of electric toothbrushes, originally coming from the Sonicare DiamondClean range, then getting annoyed at the cost when I needed to replace one, and so I went to the other end of the scale and was using the Colgate HUM brushes for a while. Now that you can no longer get those, I needed to hunt for a new one. The Sonicare 4100 seems a decent compromise for a known product that won't break the bank. You can run this thing without the charger for multiple days, it's easy to use with the standard one-button approach, and it does a good job of getting into all areas of the mouth.

I’ll never go back to a regular toothbrush again. Perfect.

I bought two of these Philips Sonicare 4100 toothbrushes—one for my nephew and one for my niece—after their older electric toothbrushes finally stopped working. Honestly, I wasn’t sure how much of a difference they’d notice, but it’s been a huge upgrade. They both love them and are actually brushing two to three times a day now without being reminded, which says a lot. The brushes are simple to use, gentle but still feel like they’re doing a really good job cleaning. I’ve noticed they mention their teeth feel “super clean” after using them, and that’s exactly what you want, especially for kids building good habits early. These brushes are known for being effective at removing plaque while still being gentle on gums, which makes them a great choice for daily use. Overall, great value and a really solid upgrade from their older brushes. Definitely recommend if you’re looking for something reliable that actually gets used!

I've used the Sonicare products for decades. They last a long time, but my last one finally died after more than a ten years of service. Obviously, I replaced it with this. The last one just wore out, I guess. After charging for its entire time between uses, it slows down and then stops after a few minutes. Batteries don't last forever, after all. I kept the old one, though. It's great for cleaning ridges and corners in the kitchen!

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.

JUNK! Philips brand toothbrushes have become nothing more than expensive junk. My wife has one that is ten years old and works like a champ. I ordered this because it was relatively inexpensive. Plugged it in to take an initial charge, and it charged fine. Used it the next morning and returned it to the charger and it began beeping twice every thirty seconds or so. The lights kept blinking orange/yellow. Manual said to do a “reset,” so I did. Returned it to the charger and same issue…beeping twice every thirty seconds with the flashing orange lights. I contacted Philips support, and they said “sounds like a battery issue…we’ll send you a box so you can mail it to us to verify, and if it is a battery issue we’ll send you a new one.” REALLY??? It’s 48 hours old…THAT’S your warranty process??? No way. Contacted Amazon and they refunded me right away and told me to throw it away. I ordered another one - the next model up - and it was delivered the next day. Placed it on the charger since it had no charge out of the box. Green lights indicated it was charging; used it the next morning, returned it to the charger…and guess what??? SAME ISSUE! I honestly think these USB chargers they throw in there are doing the damage…They’re cheap and probably unstable power delivery. I’ve tried USB outlets, different outlets and USB adapters all throughout my house…nothing. My wife’s is a normal household plug charger, and there has never been an issue. BUYER BEWARE
