[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.] I received the Oral-B iO Ultimate Clean Refills free for my honest review. Unfortunately, I was unable to use these because they didn’t fit my toothbrush. I need to buy the correct toothbrush to fit the heads but I have used this brand before and I do feel it is one of the better brands out there and as soon as I’m able to find the whole system I will update my review. I really do enjoy this brand and feel that it is great quality.

[This review was collected as part of a promotion.] I love these so much! These are perfect for my toothbrush. I have a smart toothbrush by them and these refills are so expensive so I was so happy to receive them. I have to change them always and these heads are very great so I highly recommend them

[This review was collected as part of a promotion.] As expected, the brush quality really good. The brush head gives good quality feel when you actually hold it Brush are soft enough that won’t hurt your gums I understand they want to keep each brush separately for storing long term, hower the package feels like it’s too much plastic. They could wrap or pack each individual brush in more eco-friendly material rather than hard plastic and cardboard. It’s also difficult to open too :(

[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!
