[This review was submitted after receiving an incentive.] 2 years ago I made the decision to change from a manual toothbrush to an electric toothbrush. At the time, I didn't know there are electric toothbrushes and ELECTRIC TOOTHBRUSHES!! I changed to the IO2 this past year and have never looked back. I used the standard heads up until trying the new gentle heads. This past week, I have flossed then brushed my teeth twice a day. I have found the heads nice on my gums and had an overall clean feeling after. I would absolutely use these head in future over the standard ones but equally had no major issues with the standard ones.

In fact I got one for all the family. The toothbrush heads give a great clean whilst being gentle in the gums. Get that dentist clean feeling every time I use them.

[This review was submitted after receiving an incentive.] I've been using the Oral-B iO Ultimate Clean brush heads for a few weeks now, and the difference compared to standard brush heads is incredible. The bristles are angled perfectly to reach between teeth and along the gumline, and I can genuinely feel the deep clean after every use. My mouth feels like I've just come from a professional cleaning. The brush head design also helps reduce plaque build-up -- I've noticed my teeth stay smoother throughout the day. They snap easily onto the iO handle, and the bristles hold their shape really well even after several weeks of use. Another thing I appreciate is the indicator bristles that fade over time, reminding me when it's time to replace the head -- a small touch that makes maintenance effortless.

[This review was submitted after receiving an incentive.] This is a great pack including brush heads to last 1 year. They clip onto my electric toothbrush easily and securely. They give a very thorough clean of my teeth and I know when it's time to change brush heads as the blue bristles turn white.

The toothbrush heads have made a noticeable difference in how clean and fresh my teeth feel after brushing. The toothbrush head have dual lengths bristles. It glides over every part of your teeth and reach into those tricky are effortlessly. My teeth looks visibly brighter and removes plaque effectively. It feels like a professional clean every time. Highly recommended!

[This review was submitted after receiving an incentive.] I was impressed with my first impression of the oral b replacement heads. I've tried out the Ultimate clean brush heads and I noticed a fresher and more clean feeling from using this brush head straight away. It gives a far more superior clean than using a regular toothbrush, and I really love my oral b toothbrush. I have been using the product for over a week now and I really feel like my teeth have had the ultimate deep clean.

[This review was submitted after receiving an incentive.] I love the all paper packaging. The toothbrush head texture feels firm but soft to the touch. When I used it for the first time, I feel it reached more area than the variant that I've used before. Even the hard to reach places that I need extra effort and maneuvering in my old toothbrush. This variant is pretty straight forward, you just need one movement and the toothbrush head does the job for you. I feel some buildup around the back of my teeth and after two weeks of using this, the build up is gone. And my teeth feels cleaner than it was. And after weeks of using, the texture of the toothbrush head is still firm. I know that this brand will last longer and is a good value for money. I would definitely recommend this toothbrush head especially to people who can see and feel build-up around their teeth because it does clean deeply and effectively.

[This review was submitted after receiving an incentive.] I received this free, but this is my honest review. They are perfect fit, easy to change and fit perfectly in my travel case. Couldn't believe the difference when I changed the head!! It's now on my calendar to remind me to do often. Mouth has never felt cleaner. 10/10 and great value with 4 heads
