Brush Master
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!

Much Cleaner Teeth
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.

Clean as can be
The Philips Sonicare 3100 Power Toothbrush has completely changed my hygiene routine. I feel so much more confident at the start and end of my day, knowing all the grime has been stripped from my teeth. Simply running my tongue across my teeth after brushing makes it clear just how clean they are. My favorite features of the brush are SmartTimer and QuadPacer. I will admit that 2 minutes feels like a lifetime when it comes to brushing my teeth, and prior to using a toothbrush with a timer, I’m pretty sure I wasn’t giving my teeth the full 2-minute cleaning they deserve. The timer and QuadPacer help me feel confident that I’m spending the recommended 2 minutes brushing and giving each area of my mouth the proper amount of attention. This toothbrush takes away all the brainpower, which I really appreciate. I also love the sleek design and black color, which look great on my bathroom counter. I would definitely recommend this toothbrush because it makes brushing effortless while giving me confidence that my teeth are truly clean. Thank you to the Stellar Product Testing Panel for giving me the opportunity to test this product.
