[This review was collected as part of a promotion.] I've had this toothbrush for a while and it works really well. It's not always easy to find the replacements, and make sure you know your model when you're looking! Though the replacements are a bit pricey, overall this is a good brush.

[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.] 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.] This OralB refill brush head is easy to remove and convenient, the head rotates in multiple directions, the bristles are not too hard, clean deeply, when the blue color turns white, it should be changed.

[This review was collected as part of a promotion.] I love this toothbrush head. It makes my teeth and gums feel cleaner then anything I have ever used. I feel like it is scrubbing my tears but not to hard and it is massaging my gums, but ina good way. My teeth feel so clean and healthy.

[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.] I bought these refills to try out and they work really well. They were inexpensive and were easily found at the store. I recommend this product.i have purchased others but this seems to be a better product

[This review was collected as part of a promotion.] I love the cute brush . They cleaned my teeth really good. I highly recommend these replacement brushes. My teeth feel clean after using this product. I would definitely buy this again. The price is great.

[This review was collected as part of a promotion.] I have used an electric toothbrush for years and this one is the best one yet. The bristles are soft enough that they don’t feel like they’re cutting your gums and hard enough that you feel them working. Great product!

[This review was collected as part of a promotion.] I really do love these because it helps me make sure my kids are getting their teeth clean. They are great and easy to use. My kids have no trouble changing out the heads like others we have tried. I would recommend these to anyone.
