[This review was collected as part of a promotion.] The iO Brush set sensi white gives a better brush than the usual manual brush. No discomfort while brushing as I have very sensitive teeth and gums. Very easy to use. I would definitely recommend this product to use everyday.

[This review was collected as part of a promotion.] I purchased these to go along with my toothbrush, and I really liked them! The bristles are very comfortable to use, and clean my teeth well. The application of the toothbrush head to the main part is very easy to do, and the toothbrush is very durable.

[This review was collected as part of a promotion.] I purchased these brush heads for my son. However, he has decided to continue using his manual brush since he has braces and doesn't feel that these allow him to apply as much pressure to his teeth. Bonus for me - I'm using the brush, instead! The brushes really seem to be doing a great job cleaning my teeth, especially along my gumline. I've always brushed my gums while brushing my teeth as I had issues with swollen gums when I had braces as a teen. These brush-heads really feel like they stimulate circulation in the gums and brush away the plaque well.

[This review was collected as part of a promotion.] Got these in the mail and they worked great, they were compatible with the electric tooth brush I had so I didn't have to go out and get a new tooth brush. Overall I'm very pleased with how they feel on my teeth as well as on the brush.

[This review was collected as part of a promotion.] These brushes are the exact quality I expect from Oral B. These brushes do an excellent job cleaning my teeth and are not too firm. They are comfortable and do not cause any mouth irritation. It’s nice they come in a two pack so you have an extra on hand

[This review was collected as part of a promotion.] Left my teeth feeling cleaner and smooth. Love the design and easy to use. Very durable material. Best product around for cleaning your teeth. Definitely would love to find these in stores as a replacement when it is time to change the head.

[This review was collected as part of a promotion.] I confess. My teeth are not the best. I have gingivitis. Which leads to bleeding gums, sore mouth and dreading brushing. The Sensi heads are the best for a sensitive mouth. I don't bleed anymore. I don't dread brushing.

[This review was collected as part of a promotion.] I recently decided to switch my toothbrush to the Oral-B toothbrush. I've been very pleased with the iO Brush Set Sensi White heads. I feel as though since using this product, my teeth feel cleaner & my gums feel healthier. This brush, with having the smaller round brush head, makes it easier get into the tough spots. It's also not so rough that it hurts my gums when I brush. The technology is amazing, too. The fact that you can download an app that monitors your brushing habits & can essentially teach you how to brush correctly blows my mind! The only downside is that they are more expensive than other comparable products.

[This review was collected as part of a promotion.] I'll be honest, I didn't realize this required the iO toothbrush (which hasn't even been released yet - is this a test?!) but here goes. 2 ct packaging is difficult to open with no perforated tab. Individual brushes do have a perforation but it was difficult to see and I did not realize until I had already tore it open. So I just tried manually brushing with the brush head and the first thing I noticed is the shape of the brushhead is much rounder than what I'm used to. It does fit around your individual tooth better though, would need the iO toothbrush to fully determine effectiveness.

[This review was collected as part of a promotion.] I love the IO brush and these brush heads are great for ensuring you get the maximum benefit from your brush. As a person wearing braces I am very particular in the brush I use and its ability to provide the effective cleaning I need. I was very satisfied with these brush heads as they gave me a clean that I could feel on my braces. Using these brush heads provides a significant improvement over a normal toothbrush and most of the electric brushed with replaceable heads I have used. My teeth are thankful for these brush heads and I will be using these consistently go forward.
