Philips Sonicare 4100 Power Toothbrush, Rechargeable Electric Toothbrush with Pressure Sensor, Black (HX3681/24)

[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.

[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.

[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!

[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.

I had the previous version of this model. This one is MUCH improved in that the brush head runs faster. It communicates with the handle when you need a new brush head. It has a battery timer warning which is VERY useful. It was not on the older version. Overall this is a great toothbrush. Especially at 40 bucks!

[This review was collected as part of a promotion.] Excellent product that is working better than expected! The gadget stays charged and the brushes remove all residue from the surface and between the teeth. The brush head is the perfect tension for the removal of residue but doesn't damage the gum surface. The ability to reach areas between the teeth and remove debris has improved using this product.

[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.

It's a nice electric toothbrush but it is not that powerful. It has a low and high vibration setting. The high setting is not that much different than the low setting. My last toothbrushes high setting was very strong however it cost 3 times more. I decided to try this one because of the price. I will use it but next time I will spend a bit more for the powerful vibration high setting.

[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.

[This review was collected as part of a promotion.] The quality of the Sonicare brand isn't anywhere near what it once was. I had purchased a new 4100, a lower end model to be sure, since the one I had bought around 2020 didn't disappoint. The moment I charged it up and turned it on I knew that the device had been significantly downgraded. It was like brushing my teeth with a toy. I bumped it up to full power, but it was still limping along. Needless to say I returned it. My husband did some surgery on my original 4100 and replaced the battery (not for the faint of heart), but my teeth and I are much happier.
