[This review was collected as part of a promotion.] I was really hoping these would be compatible with the sonicare toothbrush that I already own. Unfortunately, they were not. They do look like they are very sturdy and would last a long time. I love the smaller circular cleaning brush. It seems like it would make it really easy to get in between your teeth and be super effective.

[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 they truly deliver on every front. The bristles are firm yet gentle, offering a comfortable clean that doesn't irritate my gums. They're completely scentless, which I appreciate, and they feel like a premium-quality product. Each head lasts a long time without wearing down, so the durability is outstanding. Most importantly, they leave my teeth feeling professionally cleaned every time. Definitely worth the price for the value and effectiveness.

[This review was collected as part of a promotion.] I've been using the Oral-B iO Replacement Brush Heads for a while now, and I'm really impressed with their effectiveness. They clean thoroughly and reach all the tricky spots, leaving my teeth feeling like I just came back from a dentist appointment. The durability is also excellent-each brush head lasts several weeks without losing shape or performance. In terms of comfort, they're gentle on the gums but still provide a deep clean, which is perfect for someone with sensitive gums like me. They offer great value for money, especially considering the quality and performance. I also appreciate the packaging-it's neat, hygienic, and easy to store the extra heads without them getting dusty. Highly recommend these for anyone using an Oral-B iO toothbrush!

[This review was collected as part of a promotion.] I received these oral b io brush heads in exchange for my honest review! I'm really excited to try these! My parents both have one, but I don't have the base yet. I'm really grateful and can't wait to see the results of switching from my regular oral b brush to this!! Thank you!!

[This review was collected as part of a promotion.] My teeth are the cleanest they've ever been! These IO replacements are a great value, easy to install and don't require any scissors to open. The brush head is soft but cleans very deeply leaving my teeth feeling dentist cleaned after each brush!

[This review was collected as part of a promotion.] I was amazed! I've given each brush to my family members, and they're all happy with it. They don't hurt my gums, they clean between teeth very well, the bristles are soft, and if it wears out too much or needs replacing, it's extremely simple and safe. With just one click, I feel confident that it won't fall off. This pack is 4 brush heads at reasonable price, I don't need to spend on the whole brush when it needs to be changed.

[This review was collected as part of a promotion.] Effortless Comfort Meets Deep Cleaning Ever since I tried to the Oral-B iO Ultimate Clean refills, brushing my teeth has felt noticeably more thorough and gentle at the same time. These brush heads are incredibly soft, but they don't miss a thing they glide along my teeth and gums with just the right amount of pressure, giving me that polished, deep clean sensation without any irritation. What really stands out to me is the color fade indicator. As the blue bristles slowly turn white, it's a subtle but smart reminder to replace the head no second guessing, no tracking dates. It's a small feature that adds a lot of convenience to my routine. The brush heads click onto my iO handle effortlessly, and the design feels really intentional. You can tell it's made with precision and comfort in mind. Each use leaves my mouth feeling exceptionally fresh, and over time, I've come to really trust these for maintaining that clean, healthy feeling.
