[This review was collected as part of a promotion.] These brush heads worked great as replacements for my Oral-B toothbrush. The bristles are soft on your gums but hard enough to leave your teeth feeling clean. Would definately recommend if you are looking to replace your electric toothbrush head.

[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.] My teeth are the cleanest they’ve ever been! These IO replacements are a great value, easy to install and don’t require any scissors to open. The brush head is soft but cleans very deeply leaving my teeth feeling dentist cleaned after each brush!

[This review was collected as part of a promotion.] I absolutely love my Oral B IO toothbrush! The brush heads are comfortable while brushing and have long durability. Packaging was easy to open and of course the brand is trusted and loved. Great value with the pack of 4. I have experienced great Oral care while using Oral B.

[This review was collected as part of a promotion.] I picked the wrong brush. When I tried to attach the brush head to the stem of my toothbrush it did not fit. So I cannot give a fair review of this item. But what I can say is the brush head is lightweight.

[This review was collected as part of a promotion.] Thank you try it for the chance to try this brush. My teeth feel clean. The brush is soft . I would reccomend people to use this brush for a fresh clean feeling mouth. Its circular motion makes your teeth cleaner and helps get rid of stains from coffee and tea and tobacco use.

[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 have sensitive teeth and brushes heads work great for my sensitive teeth. I really like how gentle they are yet they clean thoroughly. The bristles are dense and their unique design cleans all the curves and corner of teeth. The bristles have colour changing features that tells you changes the new head so no more guessing. It comes in a pack of four which will last me for two years. This is great value pack. I am loving these new additions to my brush.
