[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!

[This review was submitted after receiving an incentive.] The Oral-B iO brush head is soft and gentle on my gums and at the same time gives my teeth an intense clean! 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.

[This review was submitted after receiving an incentive.] This brush head is gentle but super powerful. A little miracle worker I’d say.

[This review was submitted after receiving an incentive.] Before reviewing this product I didn’t realise how much of a different a high quality toothbrush head could make but my teeth have never felt cleaner! The head was easy to add on and is easy to remove yet stays in place perfectly when brushing. The bristles are firm yet gentle and help to get into those hard to reach areas’s, they also have a great lifespan making them great value for money!

[This review was submitted after receiving an incentive.] I've never had a brush like it! It really does give the ultimate clean without all the pressure. Less pressure means the bristles don't get ruined and so the brush heads last longer. If you connect your brush to the app it keeps you updated with when its recommended to change heads so you never over use it!
