[This review was submitted after receiving an incentive.] My teeth have never felt cleaner! These heads get into all the hard to reach places without any fuss. The clean feeling last all day and, as someone who's struggled which stained teeth as an ex smoker, I feel I can see a difference since using the iO heads.

[This review was submitted after receiving an incentive.] Absolutely love this toothbrush! After using it for a week I can already see the difference and feel the difference after each clean! I love how sleek the design is, I love the multi settings on the brush and having had issues with sensitives gums and teeth, this brush uses the exact right pressure to make sure I get a good clean without any sensitivity or pain! Wouldn’t go back to my old brush at all now I love it.

[This review was submitted after receiving an incentive.] This is the best toothbrush head that I had , very gentle, just perfect for my needs!

[This review was submitted after receiving an incentive.] It’s been a long time since I’ve used an electric toothbrush and it was a different brand but this brush head really does what it says on the tin. It gives the ultimate clean. My teeth feel like they’ve had a scale and polish at the dentist and yet it’s not as abrasive as it could be against my sensitive and thinning enamel. I can’t comment on it’s whitening ability as due to the thin enamel on my teeth, nothing will improve the colour of them, however if you don’t have this it’ll do a great job

[This review was submitted after receiving an incentive.] Best toothbrush head I’ve ever had. It feels so soft that it doesn’t cause irritation on the gums, but it still has the right amount of pressure to leave my teeth feeling squeaky clean! I’m in love

[This review was submitted after receiving an incentive.] I have never had a toothbrush that leaves my mouth feeling as clean as this. I am extremely impressed by the cleaning ability of this toothbrush. My teeth still feel clean at the end of the day and are whiter; they look and feel incredible and it has only been a week. The App has me wanting to brush my teeth better as I need to get 100% coverage and I hate loosing points due to over-pressure. A fantastic brush if you’re wanting to improve your oral hygiene while having a little fun!
