Great clean with a light touch

[This review was collected as part of a promotion.] This toothbrush is very lightweight, not bulky or heavy, and starts with a very light vibration that builds overtime. It's a great introduction to an electric toothbrush as some can be too intense and almost painful. I thought it would be great for my kids or even elderly people with sensitive teeth. My teeth feel clean and smooth after using it, even at it's lowest vibration. It's much more efficient than a manual toothbrush without being overpowering. The timer holds me accountable to brush my teeth for the correct duration. Overall this is a great electric toothbrush, no unnecessary components and just the right amount of power. Thanks to the Stellar Product Testing Panel for providing me with this toothbrush.

Nice slim toothbrush

[This review was collected as part of a promotion.] This toothbrush is great at getting teeth clean. My teeth felt so smooth after brushing. I love that it is slimmer and smaller than other versions, which makes it great for travel. It didn't feel quite as strong or a vibrations as another model I've had, which might be nice for some people. One con is the charger, it's USB but doesn't include the power block, so I have to buy one separately. Overall very happy with this toothbrush. I received this product as part of the Stellar Product Testing Panel.

I Like This Toothbrush

[This review was collected as part of a promotion.] I really like the Philips Sonicare 3100. My teeth feel noticeably cleaner than when I use my manual toothbrush. I also have an older Sonicare model that I hadn't used in a while, and this one is a nice improvement because the motor is much quieter and the design is sleeker. I also really like the color of the toothbrush. The SmartTimer and QuadPacer are a nice touch because it helps me see that I'm brushing long enough and getting all areas of my mouth. My only complaint is that I wish the charger came with a wall block. Thank you Stellar Product Testing Panel for providing this product to try and review.
