[This review was collected as part of a promotion.] Thanks @influenster and @OralB. My feel insanely fresh. The difference in just a week is real, and I love how it gets into all the tricky spots. Totally worth the investment for that professional clean at home

[This review was collected as part of a promotion.] Dental hygiene is so important to your all around health. Oral-B has made it even easier to maintain a beautiful healthy smile. You can now get iO Ultimate Clean Refills in 4 pack. This is a great value for you money and extremely convenient. I tend to forget I need to pick up a replacement until I actually need the replacement. Being able to grab a pack of 4 keeps me stocked up.

[This review was collected as part of a promotion.] I could not find any difference between my original brush heads and these other than the vibration, which really did not add extra benefit. Both are top quality. The only difference I saw was the color; the new ones are black. I've had these for two weeks. switching back and forth between them. There is literally no cleaning difference between them.

[This review was collected as part of a promotion.] Love how it cleans my teeth without much effort. It is expensive but it worth it The heads does not last longer in my opinion but I am liking it anyway so far. Love that it comes with a case so you can travel with it easily.

[This review was collected as part of a promotion.] These last a long time and work so well! I have no plaque or stains anymore! They don’t hurt my gums either. They’re good value for the money and the packaging is easy to open -!: each is individually wrapped so that they don’t get exposed until you use them.

[This review was collected as part of a promotion.] Makes my teeth feel super clean and I love that the bristles change from blue to white so I know when to change the brush head. I was advised by my dentist to use a soft brush on & near my sensitive gums. This works perfectly. I was advised by my dentist to use a soft brush on & near my sensitive gums. This works perfectly, it’s durable and last a good 90 days. Doesn’t have a scent.

[This review was collected as part of a promotion.] I like these brush heads. I don’t think my teeth have ever felt so polished and clean. They are so smooth and I have definitely noticed a difference with a decrease in plaque. These are much better than a manual toothbrush.

[This review was collected as part of a promotion.] I love my Oral B toothbrush. It works well, and the replacement heads last a long time. With the cost of manual toothbrushes anymore, I'm glad I only have to purchase the heads. They clean my teeth well and they spin to get them extra clean. I'll buy these until my toothbrush doesn't work anymore.

Oral B has always been a top electric toothbrush innovator, and these heads are their flagship example. As an oral health professional I've used several generations of both Braun's Oral B and Philips' Sonicare, and they both have strengths and weaknesses. The latest iO series is Oral B's best in my opinion. It actually provides real feedback on where you've brushed, has multiple vibration strength settings, and is easy to clean and maintain. I've also used the latest Sonicare Prestige by Philips for comparison. The Philips is more compact, with a smaller brush head, and is quieter. The Oral B provides better cleaning in my opinion, and the semi-rotary action is superior to the sonic vibrations of the Philips for removing debris. The Philips works best on the maximum setting, which may actually cause sensitivity in some cases. The Oral B is equally effective at all settings, allowing the "Sensitive" settings (there are two) to be fully utilized. You are also provided more information on the toothbrush handle itself on the Oral B, with just a row of dots on the Philips. The software app is also better on the Oral B, although both are sometimes quirky with a Bluetooth connection. The Oral B software is slightly more stable in that regard, and since both brushes are "smart" AI brushes, the software becomes more important for value for your money - both brushes operate just fine with no software connection, but Oral B's app allows you to delete sessions (if you ran the brush by mistake for instance), pause the brush while using it (to rinse for example) , and run the brush head to clean it. The downside is that Oral B uses your phone's camera for "coaching," so to benefit from the app you need to be facing your phone and it occasionally loses its orientation. Still better than the accelerometer in the Philips, which frequently gets confused over whether you're brushing the front or back surface of your teeth, and has no option to record brushing the occlusal (top surface). You also are limited to 20 seconds brushing each sextant, and the app moves on whether you finished or not - the Oral B app doesn't switch sextants until your teeth are clean. All in all, a better brush and a better head than the latest Philips, for function and utility -again my opinion - but either brush will improve your brushing habits and oral health.
