Customer Ratings & Reviews

Great products, it has 2 settings. There is no adapter included since it is a new version.

This toothbrush is pretty awesome my mouth feels cleaner compared with regular ones.

Good tooth brush. Only real complaint is the battery on the previous model lasted longer between charges.

Unbelieveable toothbrush very strong vibration you can feel the clean

Highly recommended entry level toothbrush. No issues with S&H.

I really like this! It works as promised and my teeth feel clean.

I have used electric toothbrushes for years and have been well pleased. Needing a new one, I decided on this one because Philips is a brand I trust for product quality and reasonable pricing. With minor exceptions, I am well pleased with the Model 4100 (HX3681/23). Out of the box, the brush has enough charge to be used right away. However, as with most rechargeable devices, a full charge is recommended for long running. Projected time on a full charge is 14 days, which is excellent. The brush has two intensity settings. For first timers using an electric brush, it is recommended that the lower intensity be used initially so you can get acclimated to the brush. Though I am a long timer with electric brushing, I still prefer the lower intensity. Not only does it provide a comfortable brushing experience, it is also perfect for massaging the gums and cleaning the tongue. Clean gums and tongue are an important part of promoting good dental health. Very importantly, don’t forget to floss! In addition to an excellent brushing experience, there are other nice features of the 4100 (Details in accompanying manual): *A pressure sensor to alert you when you are pushing too hard. *Dentists recommend two minutes minimum for effective brushing. This brush has a built-in “SmarTimer” to alert you at the two-minute mark. *To help maximize your two-minute experience, the built-in “QuadPacer” function is an interval timer. A “map” of your teeth divides them into quadrants (upper front and back, lower front and back). If you brush according to the “map,” there will be a beep at the end of 30 seconds for each of the quadrants. If that is too high tech, no worries, the brush is still going to be your teeth’s friend. The days of getting multiple brushing heads with a toothbrush seem to be history. The 4100 comes with only one head; however, if you register your device, Philips will send you spare head for free, as well as extend the 2-year warranty. I love the performance of this toothbrush. That said, there are a couple of things that irk me. These are why I did not post a 5-Star rating. *The charger works great. I do have a problem with the exceedingly small charging stand for a tall toothbrush. If you bump the standing toothbrush, it falls over easier than it would with a little more stability. *The charging cable comes only with USB connectivity. No adapter is provided. Though I have lots of adapters, many people may not. In addition, they just might resent having to make another purchase to able to brush without plugging into a computer or other USB power source. *With small brushing heads, no matter how good they are, keeping toothpaste on it when moving it to the mouth can be a challenge. To “lock” it on, squish the toothpaste down a bit into the brush. The irksome items aside, the operating performance of this 4100 is great and worthy of recommendation.

It works great and I like the sonic sensation. I will recommend to others.

Love this toothbrush! Bought it to replace old one that wouldn’t stay charged.

Good for teenager . They love that it’s rechargable

I Would recommend, good toothbrush would buy again

Not as good as my previous Phillip Sonic 7300. Decent electric toothbrush

Does what it is supposed to do. Philips has always been reliable.

Very effective and practical. The brand has always been amazing

Light but effective brush. Leaves teeth feeling clean everytime.

Very fast charging. Highly recommend. Great price.

Doesn't compare to the quality of other electric toothbrushes, unfortunately.

Excellent product, price and quality are reasonable for the price.

The brush head feels small and It seems like the vibration is a little weak

It brushes your teeth really fast. Time is really important.
