[This review was collected as part of a promotion.] I received this toothbrush at no cost to test. It has a slim, comfortable to hold design, fantastic battery life and 4 different brush settings! It lets you know if you apply too much pressure while brushing.

[This review was collected as part of a promotion.] I received this toothbrush as a part of a research study and I was quite impressed with its function and how fresh my mouth felt after using it. The charging case is fantastic for travel as it is much more compact than comparable products and the battery life is far better than my previous Sonicare.

[This review was collected as part of a promotion.] I really like this product as it provides an effective clean and is super intuitive to use. Also, the grip is great and provides a meaningful clean. The vibrations can be too strong at times but can be controlled by switching options. I received this product for free as part of a product test.

[This review was collected as part of a promotion.] Bluetooth connectivity enables app features such as a countdown timer, daily and weekly tracking, and a counter for uses remaining on the brush head. This product was received for free product testing.

[This review was collected as part of a promotion.] I gave a Five Star rating because this electric toothbrush is a game changer! I enjoyed being able to choose from four types of cleaning for the needs of my teeth (clean, sensitive, white or gum health). The vibrating brush was not harsh on my teeth and my teeth felt very clean after brushing. I liked the fact that a little toothpaste was all that was needed to still get my teeth clean while using this toothbrush. Being able to use the Sonicare app while brushing my teeth was a major plus and very helpful! The timer made sure that I brushed for at lesser two minutes…the recommended time. The brush along with the timer in the app prompted me when to move to the next section (of six) in my mouth to get an even cleaning of all my teeth. The app kept track of my daily brushing and had lots of data about how I brushed and for how long. The app kept me on track and gave positive feedback about my brushing and also suggestions about how I might do better! The app is a wonderful addition to the brush! I liked the beeping that I heard when I placed the brush back on the charging station. It let me know it was placed properly and that it was again charge it the toothbrush. The carrying case was also handy. My only concern about the carrying case was that it didn't close securely when the toothbrush and head (which has to be separated to fit) were placed inside. I had to wrap the cord around the case to keep it closed. This might have been user error. Overall, I would highly recommend this Sonicare electric toothbrush to anyone who wants clean teeth and use of an app that helps keep you on track and motivated to have healthy teeth!

[This review was collected as part of a promotion.] If I could give this ten stars, I would. I currently have been using a Sonicare toothbrush that was sent to me for free use as part of a product test. . This toothbrush cleans like no other. I like the settings it has, with three different vibration modes. And there are also four different brushing modes, with different timers. I've only had to charge this twice, once upon receiving and another just around the two week mark.

[This review was collected as part of a promotion.] I'm definitely a big fan of this Soniccare toothbrush. I've always used a manual, and after using this for the past 2 weeks, I'm not sure how I'll ever go back! I really like that it cleans my teeth so very thoroughly. They definitely get way cleaner with this toothbrush than I've ever gotten with my manual. I really like that it massages my gums. I feel like that alone is doing a lot for me oral health, or at least it feels that way. I think the way that the app tracks you is pretty cool, but it's a pain having to remember to bring my phone to the bathroom every single time I want to brush my teeth. Also, the buzz/shut off thing that it does every 20 seconds is a huge annoyance to me. For these two reasons, I've taken off one star. Other than that, I love everything about this product! I've received this product to test and give my honest review.

[This review was collected as part of a promotion.] I received this product for free as part of a product test. I've been using it for two weeks and have been impressed with all of it's features. It's equipped with four different cleaning modes. I have also been using the app with it, which has been very helpful. It has a timer that counts down, depending on what mode you are using. It also shows you what area of the mouth that you should be focusing on, while your cleaning. The app was easy to install and so far I've enjoyed using it.

[This review was collected as part of a promotion.] I received the product for free as part of a product test. First, let me start by saying I use a rechargeable battery toothbrush. I have never used one like the Sonicare 7100 though. I love the app that you can use to track your brushing. The timer is perfect and it literally stops when the time is up. The brush is pretty powerful which I love. My teeth feel clean after brushing. The timer also has the feature if you brush to hard it will show you. It comes with a travel case which is awesome. I definitely would recommend this toothbrush! I love it! I know that investing in a toothbrush is well worth the results!

[This review was collected as part of a promotion.] I received this product for free as part of a test product study. I didn't have any expectations when trying it- but now that I've used it- I'm truly blown away! Oral hygiene is extremely important to me & I have been a lifelong Sonicare electric toothbrush fan. Up until now- I haven't been able to tell much of a difference of newer model electric toothbrushes compared to older ones. But with this one- I can definitely tell it's a lot more powerful. it sounds louder because it's vibrating harder. I can really feel and see the difference. I also like that this toothbrush is a bit smaller and the travel case is more compact. I really can't think of anything negative to say except that this is by far the best toothbrush I've ever tried!
