[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.] A few months ago, I bought the Oral-B electric toothbrush, and now I have to replace the brush heads. It's been a turning point with this brush. My teeth are whiter, it cleans better than other brushes, and it's really effective. It's not cheap, but it's worth it. It still feels like new, so it will last a few more years. Great packaging. I will continue to use this oral-b IO. It really makes a difference.

[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.] I have been using an Oral B electric toothbrush for years now, I've had a couple different models and they were both great. I really like this brush head set for them. They are firm enough that it really feels like your teeth are getting really clean. I always do the extra 30 seconds just on my front teeth as well and it feels great after.

[This review was collected as part of a promotion.] As a fellow daily user of the OralB iO Ultimate Clean refills, I can't imagine switching to anything else now! These brush heads have completely elevated my oral care routine from mundane to genuinely enjoyable. Each morning and night, I'm rewarded with that unmistakable dentist-clean feeling that simply wasn't possible before. The technology in these refills works perfectly with my iO handle, delivering those micro-vibrations that somehow manage to clean every hard-to-reach spot while being remarkably gentle on my sensitive gums. My teeth not only feel cleaner, but they actually look noticeably brighter since making these part of my daily routine. Yes, they're a bit of an investment compared to standard brush heads, but the difference in quality is immediately apparent—and my dentist has confirmed my oral health improvements weren't just in my imagination! For anyone who already appreciates these gems like we do, you know they're absolutely worth every penny for that unbeatable fresh-from-the-dentist feeling at home.

[This review was collected as part of a promotion.] I’ve been using the Oral-B iO Ultimate Clean refills for a while now, and I can confidently say they’ve taken my oral care routine to the next level. From the very first use, I could feel how thoroughly they clean — my teeth feel incredibly smooth and polished, almost like after a professional cleaning. The bristles are firm enough to remove plaque effectively, but still gentle on my gums. I have slightly sensitive gums, so finding that balance is super important to me — and these brush heads nailed it. I also love the shape of the round head; it really hugs each tooth and gets into those hard-to-reach areas at the back of my mouth. Another thing I appreciate is how long each brush head lasts. I brush twice a day, and even after several weeks of use, the bristles still hold their shape and effectiveness. Plus, the blue indicator bristles make it easy to know when it’s time to change.

[This review was collected as part of a promotion.] Never tried this spinner before and I really like it. Will be using it again. Hope the spinner works better than the manual toothbrush. I have teeth whitener that needs a lil spin on my teeth to work better. Thanks for this amazing opportunity to try before I buy more.
