[This review was collected as part of a promotion.] These replaceable heads are round and can get to hard places in your mouth. They hug each tooth giving them a great cleaning, leaving your mouth feeling clean and refreshed! I love them and would reccomend this brush set for anyone with the iO. They are a little on the expensive side but sometimes you pay more for a great product.

[This review was collected as part of a promotion.] I got this item as I was expecting to use these on my existing O-ral B power head. They are not compatible with my existing power head. In order to use these you will need to upgrade to the iO O-ral B power head. The packaging was sufficient and they arrived undamaged through the mail.

[This review was collected as part of a promotion.] I love this product because it is easy to use and it helps rush my teeth better than with my regular toothbrush I love how it spins in order to get everything out and I love how you can get replacement heads so you don’t have to buy the toothbrush in it. It is a little pricey, but it’s worth the price. I receive this product in exchange for my honest review.

[This review was collected as part of a promotion.] The replacement brushes are easy to replace and work wonders on your teeth. The brush heads really work great at brushing between your teeth and just giving you a all over cleaning like you get at a dentist office. Definitely worth it!

[This review was collected as part of a promotion.] Thanks @influenster and @OralB. My feel insanely fresh. The difference in just a week is real, and I love how it gets into all the tricky spots. Totally worth the investment for that professional clean at home

[This review was collected as part of a promotion.] Great replacement heads for the toothbrush. The one I've been using now is a perfect replacement for the orginal. Leaving your feeling refreshed and clean. If you don't have this brush and have been on the fence about getting one, get it, grab these replacement heads for a wonderful clean.

[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 like these brush heads. I don’t think my teeth have ever felt so polished and clean. They are so smooth and I have definitely noticed a difference with a decrease in plaque. These are much better than a manual toothbrush.
