Can be soft and gentle, but may also be stiff or wear down.

Holds charge for several weeks or days with minimal recharging.

Simple and convenient to use without hassle.

[This review was collected as part of a promotion.] Philips 4100 electric toothbrush is a solid choice for anyone looking for an easy upgrade from a manual toothbrush. It does a great job of cleaning teeth, leaving them feeling noticeably smoother and fresher after each use.

The product is excellent

[This review was collected as part of a promotion.] I travel. And one charge lasts about 2 weeks. The shape is comfortable in my hand and the control button is easy to use. I like the brushing timer and that I can choose to use it or cancel it. And the unit, as a whole, does a great and comfortable job of cleaning my teeth. This is reflected when my hygienist doesn't need much time to do my semi-annual cleaning.

Honestly my dentist asked me what I was doing different and I said, “it's my new toothbrush.” It cleans so well with very little effort. I have gum recession because I push too hard when brushing my teeth. This toothbrush does all the work so I don't have to push hard. I received this toothbrush on April 15th 2026 and it is currently June 2nd and I've only charged it once. I could confidently go away for the weekend with friends and not have to bring the charger. It's a game changer.

Highly recommend!! Get yours now! You won't regret

[This review was collected as part of a promotion.] Replaced my old Oral B electric toothbrush. This one is quiet, easy to use and does a better job removing stains. I also appreciate the sleek profile and small recharge base. Easy to keep clean. Love it!

terrific toothbrush

[This review was collected as part of a promotion.] My teeth are a lot cleaner and my gums are healthier. My dentist can see significant improvements in my oral health since switching to Sonic toothbrush. It is the best electric brush I have ever had. I know I am brushing the right amount of time because of the two minute timer. It vibrates when I apply too much pressure when brushing and lets me know when it is time to change brush heads.

Better oral health

Chose as previous toothbrush broke down out of warranty. Selected on price and a step up from previous brush. Finding it a good buy and doesn't loose charge quickly. Happy

Excellent good price

[This review was collected as part of a promotion.] I love the 2 speeds and the slender design. Just went on vacation without charger. Toothbrush still had full power after 9 days.

Excellent product.

[This review was collected as part of a promotion.] easy to use, does a great job, and most importantly, my dentist has been very happy with my routine checkups since starting to use the sonic toothbrush

great toothbrush

[This review was collected as part of a promotion.] I'm still debating how much I like this new toothbrush. It's thinner to hold than my previous Phillips. The actual brush is smaller, but that might be because I am used to the plaque – fighting brush which I believe is a bit bigger. However, there is no doubt in my mind that this new toothbrush is not as powerful as my previous Phillips.

The verdict is still out on my new toothbrush…

Dimitris Syrmopoulos

[This review was collected as part of a promotion.] I received this toothbrush as a replacement for a 4200 series brush that had quit working.   I don't recommend it.   it's a cheaply made product which charges via USB.   No charger included.   It literally has half the power of the 4200 model.

Cheap junk, spend the extra money for a 4200 serie
