[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.] I found this to be just right. It is easy to attach and the brush the right size to do a good clean. I didn’t find the brush too hard or too soft. My mouth felt so clean just like when you have a scrape and polish at the dentist! Easy to take off to change also. Very impressed with how right oral b have got this

[This review was submitted after receiving an incentive.] I found these toothbrush heads amazing! I felt like i'd been to see a dentist after i'd finished brushing them! My first words to my husband were "wow my teeth feel so clean!" They really got around every inch of my teeth and the texture is great too - just the right mix between soft / firm. I have found other electric toothbrushes hurt my teeth before but these heads were fine and my teeth feel so clean, smooth and look like they've had a good clean!! Would 100% recommend them!

[This review was submitted after receiving an incentive.] I took the head out of eye packaging and immediately fell in love with the sleek design and quality of the brush head. When brushing it aas gentle and got into all the places my manual brush couldn't reach. So after brushing I notice my teeth were whiter and my whole mouth felt refreshed
