[This review was submitted after receiving an incentive.] the head of the toothbrush Oralb OI Really soft on your teeth and gum line in comparison to the normal brush heads and they leave your mouth feeling cleaner as the bristles are smaller and can fit in more tight spaces.

[This review was submitted after receiving an incentive.] Ohhh wow this head is absolutely amazing, after a few days of using this I feel like my teeth is so clean and white, I actually feel like my mouth is so clean. This is definitely the best toothbrush I've ever used and this head is so perfect. I love how it makes me feel like it gives me a superior clean but also so sensitive for my teeth and gums.

[This review was submitted after receiving an incentive.] The Oral-B iO brush head is incredibly easy to take on and off and gives an incredible clean. I love the fact the app tells me when its time to change my brush head. Used in conjunction with the Oral - B iO electric toothbrush you really are getting a dentist feeling clean

[This review was submitted after receiving an incentive.] I received an Oral-B iO 8 refill with my new iO 8 electric toothbrush. They come in different colours to match the brush, so mine is a sleek black colour. They clip on easily and the bristles are soft enough for sensitive teeth whilst still achieving an extremely clean feeling in your mouth. My gums, teeth and tongue have never felt so clean! I couldn't stop brushing my tongue over my teeth afterwards! Game changer!

[This review was submitted after receiving an incentive.] These heads make my teeth feel so clean. The bristles are soft yet firm with cleaning. Gets to hard to reach places well.

[This review was submitted after receiving an incentive.] This toothbrush head is much more superior than ones I have used before. I like that it was individually packed, this is ideal for travel and the attachment to the brush handle was super easy. The angled bristles work amazingly at removing plaque, without being to harsh or making my sensitivities worse, as some brushes do; I think the size is spot on too. My teeth feel really clean from using this and I cant imagine using something else now. I will defiantly recommend to everyone!

My teeth look & feel cleaner within one week! The brush head comes on and off smoothly. Whilst the app tells me when its time to change my brush head.

[This review was submitted after receiving an incentive.] These brush heads are super simple to change, just click on and you are ready to go! The brush cleans really well, leaving my mouth feeling super clean after every brush. Each brush head lasts 3 months, and the app helps keep track of when the brush head is ready for changing.
