    Excellent Value for a Feature Filled Toothbrush

    I have had an electric toothbrush for many years now but it was finally time to replace it - I found this new Sonicare 4100 and thought I would give it a try and I am very impressed so far!! PROS: - The toothbrush itself is very slim and comfortable to hold! I was really happy with it not being too bulky, and just overall the design is really nice. - It has plenty of power! To be specific, you have two power options to choose from and both are great. What’s nice is that although it is powerful, its still quiet and feels very stable. - As I touched on, you have two power levels. Once you start the toothbrush, if you tap the power button again within 2 seconds it will change power level. So basically between a standard level and a more powerful level, but once you know what works best the toothbrush will always keep it at that level! And if you want to change, just cycle through the levels again once you start up the toothbrush. - Once you start the toothbrush, it has this internal timer that will buzz when it wants you to change the area of the mouth you are brushing. So it divides your timed brush session into four 30 sec areas to make sure you do everything correctly. Pretty nice feature! - The toothbrush can also tell how hard you are brushing and how often you are brushing to give you suggestions when to change your toothbrush head. A nice clever idea as well! - Lastly, I love how it has a 14 day battery life. That is huge to not have to charge it constantly! CONS: - The biggest con is that it does not come with a “brick” aka an outlet adapter for your USB powered charger. I get that people often have extra bricks and the toothbrush lasts 14 days on one charge, but its still something you need to make sure you have. - It also does not come with a travel carrying case. I don’t think its entirely necessary to have one, but its something to know, BOTTOM LINE: - Electric toothbrushes can get really expensive, really quickly. The Sonicare 4100 is an excellent value as it is slim yet powerful, and has a ton of extra features along with a 14 day battery life. I am very happy with my purchase and excited for my many years of use!

    Clean and fresh!

    I didn’t realize how lazy my old brushing routine was until the Philips Sonicare stepped into my life like a tiny dentist living in my bathroom. From the first use, my teeth felt ridiculously smooth — that fresh-from-a-cleaning feeling you usually only get twice a year. Now it’s every day. Twice. Like clockwork. The vibrations are powerful but gentle, almost like your gums are being serenaded rather than attacked. I love the built-in timer — it keeps me honest when my mind wants to wander off after 20 seconds. And the different modes are a blessing depending on whether I want “polish me like a diamond” or “be kind to my sensitive soul.” Battery life? A champ. I charge it, forget about it, and weeks pass before it politely asks for power again. The slim, modern design looks classy on the counter — no giant spaceship vibes, just simple and elegant. It’s one of those small upgrades that quietly elevates your life. My smile feels brighter, my breath feels cleaner, and I actually look forward to brushing — which feels like a miracle in itself. Five shining stars and a minty-fresh thumbs-up. ⭐⭐⭐⭐⭐

    Great everyday electric toothbrush

    I have been using the Philips Sonicare 4100 Power Toothbrush and it works very well. The brushing performance is strong but still gentle on my gums. It is easy to use with a simple one-button design, which makes it convenient for daily use. The battery life is also good and lasts a long time between charges. Overall, it is a reliable and effective electric toothbrush for everyday oral care.

    Much Smaller and No Charger vs Prev Gen

    I ordered another 4100 after metal piece you clip your brush onto became very loose my current 4100. When I received it I noticed it was way smaller than my current one. The 'intensity' doesn't seem to be as strong as my old one. Not sure if that's a good or bad thing. I know there are two power stages. I put it on the strongest and it's still not a strong as the older one. Took used to gripping a smaller handle but should be good in the long run. I also noticed that the end of the charger is a USB-A instead of a traditional wall plug. Some ways it's nice if you have built in USB ports in your wall outlet or perhaps traveling and use the USB ports in hotels or even in your car!! :) Downside is you need to provide your own wall connecter to charge the brush. I just use an old iPhone charge cube to charge it and it seems to be fine. Overall, love the Sonicare. My dentist agrees. The last two checkups using this vs my previous Oral-B has been noticeably better.
