Great product...highly frecommend.

Tulipmagnolia May 19, 2026

[This review was collected as part of a promotion.] My older Phillips electric toothbrush was in need of replacement and i am glad I found this newer model. It does a great job, as expected, and the newly designed brush heads are great. My mouth and my teeth and gums always feel refreshed after brushing.

Really powerful cleaning

JayBird1545 February 22, 2026

[This review was collected as part of a promotion.] I've had several different models of this brush and I must say this one tops them all. I've never had my teeth look and feel this clean! I would definitely recommend this model to anybody I know!

New brush style is an improvement

lele2 March 12, 2026

[This review was collected as part of a promotion.] I love the way the toothbrush feels in my mouth. I'm using the Clean setting and I feel like it is doing a thorough job, but never feels harsh. I miss the built in UV sanitizer and case that kept the old brush clean. I do think the new brush style is better than the old version.

Love It But Could Use Some Improvements

jaytro March 5, 2026

[This review was collected as part of a promotion.] I like how clean my teeth feel after using this toothbrush. I like that it has many different settings and that it tracks my brushing sessions. What I don't like is when I extend my brushing session, after the initial brushing is complete (only for a 20 seconds or so because I use some of the time to clean my mouthguard), it make it seem like i have an incomplete session. I also don't like that I can't connect to the toothbrush while it's charging.

Okay

Zebr12 June 1, 2026

[This review was collected as part of a promotion.] I was excited to try the Series 7100, but it wasn't worth the extra cost for me. The cleaning doesn't feel much different from other Sonicare brushes I've used, and the app adds very little value beyond confirming you've brushed for the recommended time. I was also disappointed that it only comes with a USB charger, which isn't very convenient. Thankfully, it works with my older Sonicare plug charger. Overall, it's a good toothbrush, but I could have bought a cheaper Sonicare model and been just as happy.

[This review was collected as part of a promotion.] I already provided a lengthy and detailed review for the 5 star rating I gave you. Maybe you're asking for another review because you didn't like the 5 stars.
