[This review was submitted after receiving an incentive.] This toothbrush head is absolutely excellent and works perfectly with the toothbrush. It really cleans my teeth perfectly and keeps them free of plaque all day long. I’ve noticed a massive difference in a short amount of time and can’t wait to watch my teeth improve more and more.

[This review was submitted after receiving an incentive.] Wow I can’t believe how great these toothbrush heads are! They are soft yet tough enough to provide the perfect clean! They are the perfect size and clean each tooth individually. 10/10!

[This review was submitted after receiving an incentive.] On first using these toothbrush heads they are soft on your gums but are amazing at cleaning. I love the feature the app has to keep track of when to change your toothbrush head. I'm terrible at changing the heads on my toothbrush at the correct time so this feature will really help. I've never had my teeth feeling as clean as they do after I've used these toothbrushes.

[This review was submitted after receiving an incentive.] The design of the brush head is sleek and very pleasant to use. It has a high quality finish and feels good in the mouth. My teeth feel super clean, even in hard to reach places. The brush design allows for expert cleaning and it attaches to the base perfectly. I will never go back to another brush.

[This review was submitted after receiving an incentive.] The bristles are super soft but move quickly, leaving a really gentle clean for both your teeth and your gums. The arrangement is also super perfect for managing to get into every single corner or gap - I really noticed this particularly with the back of my mouth where I have generally hard to reach wisdom teeth, but this manages to get in there no problems and also feels really gentle but thorough in the process. I can actually feel each of the different bristles hug around each tooth. Perfect!

[This review was submitted after receiving an incentive.] I like to use this head on whitening mode. It cleans my teeth really good and doesn’t make my gums bleeding or being painful.

[This review was submitted after receiving an incentive.] I’m notoriously bad at changing my toothbrush so having a reminder with the iO is a godsend. The brush heads on the refills are a perfect balance of gentle but effective. They really get in to the recesses and ensure your mouth feels fresh, clean and plaque-free. I was amazed at how polished my teeth felt after using the brush. Now I’ve tried them, I can’t see my ever going back to manual tooth brushing.

[This review was submitted after receiving an incentive.] Really impressed with the easy application of this brush head onto the electric toothbrush - no fuss! I usually look for a thick looking brush head but this one seemed to work better than ones I have used before. It's gentle to touch - even when applying more pressure on your teeth. I was happy to hear that the brushes had been recommended by dentists. It will be interesting to see how easily accessible these brushes will be to buy once they hit the market. Will definitely be purchasing more.

[This review was submitted after receiving an incentive.] The bristles are really soft and gentle on my teeth and gums. My favourite thing about them is their angle, it gets in the really hard to reach areas without a struggle. Also the bigger and smaller size bristles really help doing the teeth and between them at the same time. I definitely feel like ive steped out of the dentist after using this! Absolutely amazing.
