[This review was collected as part of a promotion.] Got these and they work wonders. Packaging was great. Easy to open and easy to install on the toothbrush. The Brussels were just right when using, they were not to soft and not to hard. Just right. Definitely worth buying more.

[This review was collected as part of a promotion.] Great for keeping my teeth feeling clean. Love that these brush heads get around the whole tooth and gum. Easy to tell when they need to be changed and I love this brush for being able to know when I’m putting too much pressure to keep my gums safe. The refills aren’t too expensive either. I’ll never switch to a different tooth brush brand this series is great!

[This review was collected as part of a promotion.] One of the best brush in market. I have tried multiple brands in past but this one is the best so far long lasting battery cleans teeth perfectly. This one even comes with carry case for travelling. definitely recommend this.

[This review was collected as part of a promotion.] Still the same round shape but removes tarter 100% better. The brush head not only oscillates, rotates and vibrates for a better cleaning...but it seems to make it easier to clean your inner teeth. This toothbrush system connects to an app to show you exactly where you brushed and what you missed and if you are brushing too hard. It is kind of hard to watch the app as you brush but this is a great idea. Overall I like the concept and it's crazy to think a toothbrush could teach you how to properly brush your teeth. It's a keeper

[This review was collected as part of a promotion.] I love these brush heads. They are not too soft or too hard. The brush head isn’t too big either. My teeth feel incredibly clean every time I use it! There’s no plastic taste and the texture not rough.

[This review was collected as part of a promotion.] I have used an oral b electric toothbrush for years. I love the smaller round brush head. I have a small jaw, so anything larger will not fit into the back of my mouth. My dentist recommended oral b and I am so glad he did. I have excellent cleanings, very little plaque. The oral b brush heads are small enough to get behind my back teeth, without a lot of discomfort. The brush head spins around to ensure that you get every inch of each tooth. The brush head cleans the gums as well, without a lot of unnecessary pressure. I am very pleased with the results from the oral b io brush heads.

[This review was collected as part of a promotion.] These are great toothbrush heads for the io series. The best of the best. Leaves your mouth with the ultimate clean. They don't last as long as you would want for the cost though but they are great.

[This review was collected as part of a promotion.] Oral-B iO replacement brush heads come in a 2 pack, thank goodness! Easy to open packaging. Simple to replace heads. I am very impressed at how clean my mouth feels! My teeth are extremely clean! This brush is so stimulating, my gums feel rejuvenated! I know my breath is fresh & I am ready to face the day!

[This review was collected as part of a promotion.] I felt it wasn’t good quality the brushes definitely did not do the job for me my teeth didn’t have a clean feeling after the brushes feel cheaply made the bristles as well. I used a few times to see if maybe I just needed to break In but still a no for me

[This review was collected as part of a promotion.] I got my replacement toothbrush heads this week and I was so excited. They worked so well that when I needed them replaced it was very easy to get. I would recommend them to any of my friends and family.
