Customers are saying

Customers consistently note the 4100 Power Toothbrush's excellent cleaning ability and long battery life as significant advantages. Many appreciate its ease of use and the included timer, while some find the brush head size smaller than expected and express concerns about the charging method and cost of replacement heads. The positive feedback on cleaning performance and battery life outweighs the negative comments regarding size and charging. A travel case is also mentioned as a missing feature by some users.

    Even though this toothbrush is smaller than my previous model, it seems to be just as powerful and does hold a charge longer (5+ vs 3+ days). We’ll see on next checkup how effective it is.

    The Phillips Sonicare Toothbrush was a great toothbrush for the price. The only complaint that I have is that the toothbrush doesn'r come with multiple heads.

    I bought this to replace my older Sonicare toothbrush. It is so much lighter! I like the option of two pressure settings. Highly recommend!

    This is a replacement for a brush that I had for the last three years. The battery lasted for several years and think you will be as content with this brush as I was.

    Great brush. I had the older one before. And this one is lighter. Only need to charge it every 2 weeks or so. My hygienist said my teeth and cleaner and my gums are in great shape

    Works very well. Had an older model that was more expensive, with many options I never used. Especially like the pressure sensor on the new one that the old one lacked.

    Unfortunately my unit was DOA. (mfr issue, not BBY) And I was on vacation during the 2 weeks return period! As I had purchased the Geek Squad Protection Plan however, I was able to exchange with BBY for another unit, which works great. (NOTE these Vibrate, ("Sonic") not oscillate like other brands) - Which apparently works for shaking particles off teeth? So far so good, will see at next Dentist appt!

    This was one of 2 brands my dentist recommended, and this model is the lowest cost Philips product that includes the 15 second timer (to help address each part of your mouth adequately) and the pressure sensor (to ensure you don't put too much pressure on your teeth or gums). Since using it my mouth definitely feels cleaner, and my wife has noticed some whitening of my teeth, even though I'm using the same toothpaste. So I happily recommend this product.

    Though the product does not have the fancy functions than more expensive ones it works well and is quite which to me are more important than other functions.
