[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’m genuinely impressed. The value for money is great considering how effective and long-lasting each head is. When it comes to effectiveness, these refills leave my teeth feeling professionally cleaned every time — noticeably better than standard brush heads. The packaging is neat, secure, and easy to store. I also appreciate the durability — each head lasts several weeks without losing its cleaning power or bristle shape. Highly recommend if you want to get the most out of your iO toothbrush!

[This review was collected as part of a promotion.] Have been very happy with this product so far.with so many to choose from,I wasn't so sure about them at first,but very glad I decided to try them.The bristles are soft enough for my gums,and also firm enough for my teeth.

[This review was collected as part of a promotion.] First the iO brush is amazing! And these replacements are great. The brusheads are SOOO much better than the other electric toothbrush I had. It seriously makes a difference when upgrading to these. They recommend you replace your brusheads every three months so these are good to have handy.

[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.] Have tried other heads and so far, this is my favorite. Some of the other styles were too harsh on my gums. This one is easier to get into some of the awkward angles and spaces in my mouth. I will definitely be using this head for the foreseeable future.

[This review was collected as part of a promotion.] I very much appreciate this pack of refills for my OralB iO toothbrush! They fit perfectly and are easy to change out. I think it's really smart that each refill brush comes in its own package so they're sealed and clean even after you open the main packaging and are easy to store until needed. It's also nice having so many refills at once so I'm not going to the store every 6 months to get new ones!

[This review was collected as part of a promotion.] These Oral-B iO Ultimate Clean refills leave my teeth feeling incredibly clean—like I just left the dentist. They’re easy to swap out, and the angled bristles reach well between teeth. A bit pricey, but worth it for the performance. Just be sure to keep them dry to avoid any mold issues.

[This review was collected as part of a promotion.] I really like these brush heads. I've used a lot of different electric toothbrushes but this is one of the best. Thee heads very easy to replace and left me with an extremely clean feeling. The bristles are soft but still do the job without hurting your gums.

[This review was collected as part of a promotion.] This product is one of my favorites. I've used it for a long time; it really keeps your teeth completely white. You don't have to pay extra, and its comfort at home is phenomenal and very durable! I highly recommend it, thank you
