[This review was collected as part of a promotion.] Very efficient cleaning power. Left my teeth feeling clean and polished. Bristles are soft and gentle yet firm to remove plaque. The circular design allows you to reach difficult spaces. These replacement heads are good value for the money, I recommend.

[This review was collected as part of a promotion.] I received these Oral-B refill heads for free in exchange for an honest review, and I’m genuinely impressed. The bristles are gentle yet effective, leaving my teeth feeling super clean without irritating my gums. The fit was perfect with my Oral-B electric toothbrush, and I appreciate the color-fade bristles that indicate when it’s time to replace the head. It’s a great value for maintaining oral hygiene with consistent performance. Highly recommend! I really like how it tells you when it change the brush head too! Makes it easy to keep an eye on it.

[This review was collected as part of a promotion.] They are so good! The packaging is nice and love that they feel durable. When brushing teeth’s it feels comfortable. When you need to change head brush, it turns white , that is so much helpful,I really just change it every month . So that is great! Comes with 4 heads.

[This review was collected as part of a promotion.] The product is very good! It has no flavor, lasts a long time, so the answers will last! Also, remember to change them periodically! The price isn't cheap, but it's worth it! And its packaging is simple.

[This review was collected as part of a promotion.] My absolute favorite toothbrush and I have bought a lot of them over the years! My teeth feel dentist appointment clean after every use. Great value for the multipack refills and they last! I’ve had my Oral-B electric toothbrush for a couple of years and the refills are sold everywhere so it’s easy to pick up refills when in need then for the whole family. My dentist also commented on how clean my teeth were at my last several visits.

[This review was collected as part of a promotion.] I’m so happy to be a part of this program, I already had a brush and got my whole family using these brushes. They work amazingly, they let us know the pressure we’re using, and the time frame. They’re a little pricy but worth the amount. I used to be upset of costs, but after purchasing this I see how worth it, it is. Definitely a must buy, worth the price, worth the results.

[This review was collected as part of a promotion.] These brush heads are awesome. They rotate when your toothbrush is on and gives you such a good clean feeling. The bristles start to turn a little white when it’s time to change it too so that’s super nice! They’re a little pricier but less expensive than getting a filling! Totally worth it.

[This review was collected as part of a promotion.] Everyone in my household uses the Oral-B iO system — myself and both of my children — so these Ultimate Clean refills don’t last long around here. The bristles are soft enough for sensitive gums but still leave our teeth feeling fresh, smooth, and genuinely clean after every use. I appreciate the color-fading bristles. With three people using them, it’s helpful to have a visual cue instead of guessing or keeping track of who’s due for a replacement. Price-wise, I think they’re fair for what you get. But how long they last really depends on your household. A 4-pack barely covers us. I usually go for the 6-pack — it keeps things simple and lasts a little longer. Bottom line? These refills are reliable, easy to swap, and they keep our brushes doing what they’re supposed to. If you’re already using the iO, just do yourself a favor and keep a box on hand.

[This review was collected as part of a promotion.] The replacement brushes are easy to replace and work wonders on your teeth. The brush heads really work great at brushing between your teeth and just giving you a all over cleaning like you get at a dentist office. Definitely worth it!

[This review was collected as part of a promotion.] I love these brush heads. They are not too soft or too hard. The brush head isn’t too big either. My teeth feel incredibly clean every time I use it! There’s no plastic taste and the texture not rough.
