[This review was submitted after receiving an incentive.] Great brush heads, easy to attach/remove, leaves my teeth feeling clean, far more than others I have used. The only negative is that I am not sure how recyclable they are. It would be good to know that.

[This review was submitted after receiving an incentive.] I’ve been test the new Oral-B iO now for around a week and have really been impressed. The brush head is gentle and have felt any discomfort. My teeth feel clean after each brush and found it cleaner better than a manual toothbrush.

[This review was submitted after receiving an incentive.] This was so easy to pop on to the io7 and to take off again to store in the case. The brush itself has left my teeth feeling so clean it like they’ve been done at the dentist! Also if you connect to the app it will give you a reminder of when 3 months is up and time to change your brush head do that it’s always in optimum condition.

[This review was submitted after receiving an incentive.] These brush heads are awesome. I love how clean they leave my teeth - I am left feeling like I have had a professional dentist clean! They are just the right thickness and size - and I love how they change colour. It makes brushing so much more fun!

[This review was submitted after receiving an incentive.] An all round amazing tooth brush head. Comparing it to my other heads for my old electric tooth brush it is miles better! The design is smart as it allows for a better clean. It makes you feel like you've had them cleaned at the dentist!

[This review was submitted after receiving an incentive.] This toothbrush is amazing. Even when you take away the cool handle with all the amazing things it can do, the head of the toothbrush is fab too. It's got big thick bristles and you can really feel it working and cleaning well

[This review was submitted after receiving an incentive.] Wow! These toothbrush heads are amazing they made my teeth feel so clean and so smooth just after one brush. The only downside is there a bit too hard for my teeth, I prefer to get sensitive heads which unfortunately it doesn't come with the box.

[This review was submitted after receiving an incentive.] These brush heads are great. They feel gentle on your gums yet still leaving your teeth feeling super clean. Love that you can buy different brush heads to colour match with your toothbrush. A gentle reminder from the app that it’s time to change your toothbrush is a nice touch too.
