Packaging says it fits Braun electric toothbrush but it it barely doesn't fit properly; it comes off where attached when running.

Perfect replacement for io toothbrush. I’ve tried the generic replacements online but they never fit just right.

I have only used it a short time..but in that time my impression is one of surprise it cleans my teeth good.

Goes well with the actual toothbrush purchase. Allows for replacement brushes through the coming year.

This ended up not fitting my Oral-B electric toothbrush -- after buying replacement toothbrushes for years, suddenly they make a new kind that apparently fits a different brush.

[This review was collected as part of a promotion.] These are such amazing love the Brissels on the toothbrush really gets my teeth clean and deepened really great plus they last for a good 4-5 months for me to change them out again and the value amazing how many you get in the pack and very soft on the teeth but cleans very well and great comfort plus they go in the toothbrush so easily

[This review was collected as part of a promotion.] I am very impressed with how clean my teeth felt after my very first brushing. The shape of the brush head allows each tooth to get thoroughly cleaned. It also felt like my gums were getting a great massage. Very impressed. If there was anything I would change it would be these two things: 1. Having a flat surface on the bottom of the replacement head. This really bugs me as I like to stand the brush head to dry in my medicine cabinet. I'm unable to do this as it's angled and have to lie it down which isn't the best option. You may ask why not just leave it on? Well, there's several of us who use it, so that's not an option. 2. Having a cap to cover the brush head in between uses. Yes, it's kept in my medicine cabinet, but it has fallen on the floor so having that extra coverage would be a great feature.

[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

[This review was collected as part of a promotion.] These Oral-B iO Ultimate Clean refills have become a staple in my oral care routine. The durability is impressive—each head lasts a solid three months without fraying. In terms of effectiveness, they leave my teeth feeling squeaky clean and noticeably reduce plaque, even around the gumline. I also appreciate the comfort—the bristles are firm but not harsh, making them great for daily use. The value for the money is fair, especially if you grab a multipack. Even the packaging feels premium and hygienic, with each brush head individually sealed. Overall, these are worth every penny for a healthy smile.

[This review was collected as part of a promotion.] My absolute favorite toothbrush and I have bought a lot of them over the years! My teeth feel dentist appointment clean after every use. Great value for the multipack refills and they last! I’ve had my Oral-B electric toothbrush for a couple of years and the refills are sold everywhere so it’s easy to pick up refills when in need then for the whole family. My dentist also commented on how clean my teeth were at my last several visits.
