My Best Experience Ever!

Luckygal53 June 21, 2026

[This review was collected as part of a promotion.] I would highly recommend anyone getting this electric toothbrush. It cleans my teeth much better than a regular toothbrush. My gums are healed too now. All the swelling is gone. I will have a much better time know getting my teeth cleaned and can't wait to do it.

Great Toothbrush in All Respects

Stating the Obvious June 23, 2026

[This review was collected as part of a promotion.] Great toothbrush at a good price. Does everything it advertises with few controls to fiddle with. Started using it several months ago and my dentist has already commented on how much better my teeth look

This Toothbrush has features that are great.

DShawano June 4, 2026

[This review was collected as part of a promotion.] This is exactly what we were looking for in a Professional Toothbrush. The different settings are perfect for both of us. We have had 3 Sonicares before we purchased this one. We have liked each one. This is over a period of 35 years.

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.

Excellent Toothbrush

BillyG65 June 6, 2026

[This review was collected as part of a promotion.] Bought the 7300 to replace an OralB. The 7300 is head and shoulders above the OrslB. My teeth never felt so clean and that feeling lasts all day/night. Wish I would've tried a Sonicare earlier..

Odd Timer

Matthew June 28, 2026

Great battery life and plenty of options for cleaning. One draw back is the timer is every 20 seconds then move to another section of your mouth. Your mouth is shown in 6 sections in the manual, but it would be nice to keep it 30 seconds for front, back, lower and upper.

The product is ok. Glad I bought it on sale.

SteveC1 July 13, 2026

[This review was collected as part of a promotion.] The toothbrush is ok. I'm not sure about the different settings, particularly the whitening setting. Ii brushes your teeth for 3'more seconds, but it doesn't whiten your teeth.

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.

Done with Phillips Sonicare

@ 5 Forks July 30, 2026

[This review was collected as part of a promotion.] Used once then it died. Toothbrush would not reset or hard reset. I returned it immediat and will purchase an Oral B. This is the third Phillips Sonicare toothbrush that has failed me. At least I got about 2 years out of my other Sonicares. No more.
