[This review was collected as part of a promotion.] The brush heads are comfortable, and leave my teeth feeling nice and clean. I use whitening toothpaste, and at this point I can't say whether these heads make my teeth look whiter as I've only been using for a couple weeks, but I like the heads and will continue to use whether they whiten or not. They're similar to other whitening toothbrushes, but they're designed for power toothbrushes, so I assume they'll work better than others. Give them a try, they work good and are comfortable, not too hard on my teeth or gums.

[This review was collected as part of a promotion.] I received these brush heads free in exchange for my honest review. I love the iOS toothbrush and these brush heads are all I have used so far. I love how clean my mouth feels after brushing. This is much more thorough than a manual toothbrush. While overall the toothbrush is pricey, you make up for it in the long run as you won’t be replacing a toothbrush but rather just the brush heads AND I would think you will get better dental reports based on how much cleaner it makes me feel. I love that these brush heads turn white with use so you know when to replace them. That feature is a money saver in my mind. Lastly I like that the brush itself is soft and paired with the features is this toothbrush, it is much easier to know you are brushing with the correct pressure and for the correct amount of time. My husband uses this too and we plan to upgrade our kids next.

[This review was collected as part of a promotion.] The Oral B IO Ultimate Clean Refills makes brushing your teeth actually fun! The brush heads feel so good in my mouth, and it helps me feel like my teeth are getting a massage. They are very easy to put on/take off on the toothbrush. They last about 3 months, and are not that expensive to purchase.

[This review was collected as part of a promotion.] These Oral-B iO Ultimate Clean refills have become a staple in my oral care routine. The durability is impressive—each head lasts a solid three months without fraying. In terms of effectiveness, they leave my teeth feeling squeaky clean and noticeably reduce plaque, even around the gumline. I also appreciate the comfort—the bristles are firm but not harsh, making them great for daily use. The value for the money is fair, especially if you grab a multipack. Even the packaging feels premium and hygienic, with each brush head individually sealed. Overall, these are worth every penny for a healthy smile.

[This review was collected as part of a promotion.] These give a super deep clean and feel really gentle on the gums—no irritation at all. You can tell the difference right away compared to regular brush heads. They're a bit pricey, and only fit iO models, but honestly worth it if you want that fresh-from-the-dentist feeling every day.

Been using the iO7 for about a year and love it. What disappoints me is the brush head. Purchased the package of 6 from Sam's and every single one has broke within a month. There is a tiny piece of plastic with a magnet attached inside the head that breaks off. I do not drop them, or hit them against the sink. I am very gentle with them. I'm on my last brush head and needing to purchase more. Hope the Oral-b rep read this and take my suggestion back to the design board to make the internal pieces stronger. They are too expensive to have to replace every month.

[This review was collected as part of a promotion.] I got my replacement toothbrush heads this week and I was so excited. They worked so well that when I needed them replaced it was very easy to get. I would recommend them to any of my friends and family.

[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.] Dental hygiene is a super important part of my daily life, so I was thankful to have recently received the Oral-B iO Ultimate Clean refills. The replacement heads come four to a pack, and although they are a bit more expensive, they are worth it. The Oral-B iO Ultimate Clean electric toothbrush head delivers a superior clean with its twisted and angled bristles, effectively removing plaque and leaving teeth feeling smooth and gums feeling healthy. Another great feature I love is that the bristles turn white from blue when they need to be changed. Overall, they are great quality, and durable, and my teeth are so much cleaner than other similar options I have used.
