[This review was collected as part of a promotion.] I’ve used electric toothbrushes before, but the Oral-B iO with the Ultimate Clean brush head has been a completely different experience — in the best way. Right away, I noticed my whole mouth felt cleaner, not just my teeth. The brush head does a great job reaching along the gumline without being too harsh. I’ve had a problem with my gums bleeding in the past, but this has not been an issue with this brush . It feels gentle, and my gums have actually felt better and healthier since switching to this. One thing I really like is that the brush heads come individually wrapped, which is great for hygiene and makes it easy to store extras or share a pack with others in the household. These brush heads seem to be a little pricier than my older model, but so far it seems worth it. If you haven’t switched, I think you should give these a try, you will notice a difference.

[This review was collected as part of a promotion.] I already had the Oral-B iO and was obsessed with it .It did not disappoint! It leaves my teeth feeling super clean and polished, almost like I just left the dentist. The bristles are firm enough to be effective, but still gentle on my gums.

[This review was collected as part of a promotion.] Love my Oral B io refills. It gives a fresh, cleaning feel every time. I change mine every 3 mos so they last and they’re a great price as well. Packaged well so you can see the brush bristles well.

[This review was collected as part of a promotion.] This brushes are so cool. They are worth your money. Package comes with 4 brush head replacements. They are durable and very effective to brush teeth. Brush is soft and comfortable for cleaning teeth

[This review was collected as part of a promotion.] The replacement brushes are easy to replace and work wonders on your teeth. The brush heads really work great at brushing between your teeth and just giving you a all over cleaning like you get at a dentist office. Definitely worth it!

[This review was collected as part of a promotion.] I received this product in exchange for my honest review I've had this same brush heads with my iO 7 for approximately two years now and I've been satisfied with them. They clean all areas of the mouth including those tricky areas at the back efficiently. The brush heads are plastic and are relatively strong and last a reasonable amount of time, which makes the price worthwhile. The packaging is neat and easy to open which is a plus. One of the features I like is recognizing when to change the head, the color on the bristles fades to white means it is the time to change so there is no need for guesswork. I usually change the heads every four months, but they definitely do what I need. I will say they are a bit firm. It's ok for regular teeth but if you happen to have sensitive gums, they may be a bit rough. If you're looking for a good clean and don't mind a firmer feel, this is a great option. I recommend this product.

[This review was collected as part of a promotion.] These give a super deep clean and feel really gentle on the gums—no irritation at all. You can tell the difference right away compared to regular brush heads. They're a bit pricey, and only fit iO models, but honestly worth it if you want that fresh-from-the-dentist feeling every day.

[This review was collected as part of a promotion.] I felt it wasn’t good quality the brushes definitely did not do the job for me my teeth didn’t have a clean feeling after the brushes feel cheaply made the bristles as well. I used a few times to see if maybe I just needed to break In but still a no for me

[This review was collected as part of a promotion.] These replaceable heads are round and can get to hard places in your mouth. They hug each tooth giving them a great cleaning, leaving your mouth feeling clean and refreshed! I love them and would reccomend this brush set for anyone with the iO. They are a little on the expensive side but sometimes you pay more for a great product.

[This review was collected as part of a promotion.] I love these so much! These are perfect for my toothbrush. I have a smart toothbrush by them and these refills are so expensive so I was so happy to receive them. I have to change them always and these heads are very great so I highly recommend them
