Brush Master

momoffour — 5 out of 5 stars

[This review was collected as part of a promotion.] We are a Sonicare household and the Sonicare 3100 is another great addition to our family’s toothbrush collection. It’s a great toothbrush that buzzes every 30 seconds to indicate when to move to a different area. I love that it’s an easy way to help keep track of where you are and how long you’ve been brushing. The Sonicare toothbrushes we have all use the same brush heads which makes swapping everyone’s at the same time a breeze. The charger is really compact and doesn’t take up a lot of room on the counter which is a huge plus. The charge seems to last a long time with regular brushing. I recommend the Sonicare 3100 as a great toothbrush that’s easy to use! Thanks to the Stellar Product Testing Panel for allowing me to test it!

Powerful Clean With Helpful Timer

RBee — 4 out of 5 stars

[This review was collected as part of a promotion.] This is my first experience with a Sonicare toothbrush. It can feel a bit strange at first because the sonic waves sort of tickle and you move the brush differently than a manual toothbrush. There's a bit of an initial learning curve, but the brush itself accommodates for that by starting on a lower setting and rising over time. After a few brushes you adjust to how it feels and can get a better sense for how to maneuver to get an optimal cleaning. Once you feel comfortable using it, the Sonicare 3100 packs a lot of power! My teeth feel very clean without needing to press hard or spend forever making little circles. The brush is gentle despite the power level, no bleeding gums! The star features are the QuadPacer and SmartTimer, which are excellent. You're supposed to brush your teeth for two minutes each time you brush, and the SmartTimer integrates that into the brush, so if you've got it on it turns off after those two minutes. This is an awesome built in feature that helps keep me focused on actually brushing and eliminates the need to keep my phone by the sink running a timer. I feel more focused by not staring at a count down, and brushing goes much faster when I'm not looking at the clock. The QuadPacer does a little vibration/beep at you to indicate it's time to brush a different quadrant of your teeth, so during that timer all your teeth get equal attention. My one note here is that to me personally the beep isn't always very obvious and occasionally I miss it. But I really enjoy the features on the Sonicare 3100. It's made brushing less of a chore while also improving the way that I brush. My favorite element is the QuadPacer, I really feel like I'm brushing my teeth more evenly. It can take some getting used to, but when you do, I definitely feel you get a better clean for less effort than a regular tooth brush. I received my Sonicare 3100, with gratitude, courtesy of the Stellar Testing Program.

Much Cleaner Teeth

Stevie — 5 out of 5 stars

[This review was collected as part of a promotion.] I received this toothbrush through the Stellar Product Testing Panel, and I really enjoyed it. I've owned a handful of electric toothbrushes in the past, but switched to manual toothbrushing only a few years ago. A few things stood out right away. The first is that my teeth were noticeably far cleaner than I have ever gotten them with a manual toothbrush. Literally, the toothbrush removes a gritty film from my teeth, leaving them feeling significantly smoother, almost like they had been polished. The cleaner feeling alone makes it a keeper for me. Another nice feature is the timer function. I have no idea if I brush for two minutes or not with a manual toothbrush, but that's my goal. The timer on this toothbrush, with integrated beeps at 30 second intervals, makes it dead simple to ensure I'm spending the necessary 30 seconds on each quadrant of my mouth. Another noticeable improvement over my old electric toothbrushes is the vastly improved battery life. I used it right out of the package, and without any charging it's still going strong after over 2 weeks. One con: I was surprised by how loud it was. My overall feeling is that the toothbrush and its integrated timer left my teeth noticeably cleaner. I recommend it.
