[This review was collected as part of a promotion.] Well... how can you review these? They fit oral b... but none of my other electric toothbrushes so make sure if you have an off brand toothbrush these heads fit. Other than that they are great. The bristles are gentle and reach deep between the teeth. These are a reason ill never have a manual toothbrush again.

[This review was collected as part of a promotion.] These toothbrush heads are working really well. I have very sensitive teeth and I am not having any issues with these heads. The bristles are soft and they fit well on my electric toothbrush. I will continue to use them in the future.

[This review was collected as part of a promotion.] I bought this item to try a different tool than I was use to. It proved to be a good choice. The head attached easily and worked well with my brushing. It was easy on my teeth and cleaned them well. The ease of use and the feeling on my teeth was exceptional, I was very pleased with the outcome.

[This review was collected as part of a promotion.] The Oral-B IO is a very nice brush attachment, It is very smooth on your teeth when you happen to hit your gums it does not hurt or irritate me because the brussels are soft enough to clean well but not hurt or cause bleeding. They are very easy to use and clean well. i find using these are much better then a traditional tooth brush i feel it gets in between the teeth well and cleans your teeth very well. Its well made and is quiet during use. I think it is an excellent value.

[This review was collected as part of a promotion.] We got the tooth brush heads in excellent condition and they look really nice! I wish I cud give more of a review on this, but we do not use these styles of tooth brush heads, otherwise I would. I am thinking of giving the package to my sister in law, and see if they use this kind.

[This review was collected as part of a promotion.] After using the iO Brush Set Sensi White for 1 week, I can honestly say my smile was brighter. My teeth feel incredibly clean the brushes helped with my plaque build up. The brush was easy to attach and detach.

[This review was collected as part of a promotion.] I found the Oral B iO Brush Set Sensi White 2ct replacement brush heads phenomenal. The replacements heads were easy to replace and my toothbrush was just like new. My teeth have never felt more clean!

[This review was collected as part of a promotion.] Talk about a toothbrush set that really gets your mouth clean! This set does a great job getting the deep and stuck on pieces of food and gunk off your teeth. Leaves them feelings clean, white, and just like you left the dentist! Would highly recommend!

[This review was collected as part of a promotion.] The Oral-B iO replacement brush heads are absolutely wonderful. I love how clean my teeth feel after using this!! I can tell a major difference since I started using this! I will continue to buy these in the future. I definitely recommend these.

[This review was collected as part of a promotion.] This brush is easy to attach to the brush and it works very well. It looks just like the pictures with the small round head. These brushes arent too big so they are easy to use and they reach the teeth in the back. My teeth felt nice and clean after use. I would recommend these for someone looking for a brush set for their toothbrush.
