[This review was collected as part of a promotion.] This is the best toothbrush I have used by far. My teeth felt so clean after brushing. I feel my overall mouth health has improved. My smile is brighter. It like gets in there and cleans all the tough spots regular toothbrushes miss.

[This review was collected as part of a promotion.] As a professional woman over the age of sixty, oral health continues to be one of the number one practices I maintain through using the Oral B products. Now with the iO technology in the electric toothbrush and the accompanying replacement heads, I give myself the best self-care possible. The straightforward design of the heads and the pressure sensor lights up when you brush too hard, too soft, or just right. I like that. It keeps me honest on my nightly routine. My favorite aspect is that the toothbrush head is noiseless with the rotation and oscillation movement, so as to not awaken my husband while I brush. Overall, excellent design, and excellent product, Oral B!

[This review was collected as part of a promotion.] These are perfect. I love this toothbrush and have been using it for about 2 years. I love these brush heads along with my iQ toothbrush. Clean results, without any discomfort of being too harsh on my gums, and they’re a lot less expensive than other brands’ refills are

[This review was collected as part of a promotion.] Oral-B iO replacement brush heads come in a 2 pack, thank goodness! Easy to open packaging. Simple to replace heads. I am very impressed at how clean my mouth feels! My teeth are extremely clean! This brush is so stimulating, my gums feel rejuvenated! I know my breath is fresh & I am ready to face the day!

Best brush head I've Ever had! Why? Because it reaches really really well in between teeth and leaves your entire mouth feeling super fresh & clean. I've tried the Ultimate whitening replacement brush head and it's nothing special. It really can't compare to the Ultimate Clean brush heads.

[This review was collected as part of a promotion.] I love the Oral-B electric toothbrush because of these head toppers! they are soft and fit perfect on the teeth for better cleaning! durable and lasts a long time before needing to change another.. a 4 pack will last you a year!

[This review was collected as part of a promotion.] Love my Oral B io refills. It gives a fresh, cleaning feel every time. I change mine every 3 mos so they last and they’re a great price as well. Packaged well so you can see the brush bristles well.

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.

[This review was collected as part of a promotion.] #incentivized This Oral-B toothbrush head is really nice, I like the way the brushes are on like an angle and they’re thicker. It really feels clean when you’re finished brushing your teeth. However, I must say that it’s quite bulky and probably won’t continue to use it because it feels like something massive is trying to brush my teeth and it’s hard to keep the toothpaste in my mouth till I’m done brushing. I was able to receive this product complementary from influenster to try and give an honest review

[This review was collected as part of a promotion.] These are great toothbrush heads for the io series. The best of the best. Leaves your mouth with the ultimate clean. They don't last as long as you would want for the cost though but they are great.
