[This review was collected as part of a promotion.] Pretty good. Works great. The 4 heads are a good deal. The packaging is nice and sleek. Doesn’t hurt my gums. Durable hasn’t broken. I was getting away from electric toothbrushes but I like this one.

[This review was collected as part of a promotion.] The Oral B IO Ultimate Clean Refills makes brushing your teeth actually fun! The brush heads feel so good in my mouth, and it helps me feel like my teeth are getting a massage. They are very easy to put on/take off on the toothbrush. They last about 3 months, and are not that expensive to purchase.

[This review was collected as part of a promotion.] The OralB refills are fit perfectly with my OralB toothbrush handle and I love how they clean my teeth. The noise level is quite, the brushes feels soft. My teeth looks clean and I have no issues with the refills. I received this product from Influenster complimentary in exchange for my review.

[This review was collected as part of a promotion.] I am very impressed with how clean my teeth felt after my very first brushing. The shape of the brush head allows each tooth to get thoroughly cleaned. It also felt like my gums were getting a great massage. Very impressed. If there was anything I would change it would be these two things: 1. Having a flat surface on the bottom of the replacement head. This really bugs me as I like to stand the brush head to dry in my medicine cabinet. I'm unable to do this as it's angled and have to lie it down which isn't the best option. You may ask why not just leave it on? Well, there's several of us who use it, so that's not an option. 2. Having a cap to cover the brush head in between uses. Yes, it's kept in my medicine cabinet, but it has fallen on the floor so having that extra coverage would be a great feature.

[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.] The ultimate clean oral b tooth brush heads leave my mouth feeling so clean! Just like I just left the dentist! They are individually packaged making them easy to store and to ensure they stay clean! They are so durable and last so long! I’d definitely recommend.

[This review was collected as part of a promotion.] These are such amazing love the Brissels on the toothbrush really gets my teeth clean and deepened really great plus they last for a good 4-5 months for me to change them out again and the value amazing how many you get in the pack and very soft on the teeth but cleans very well and great comfort plus they go in the toothbrush so easily

[This review was collected as part of a promotion.] I was really hoping these would be compatible with the sonicare toothbrush that I already own. Unfortunately, they were not. They do look like they are very sturdy and would last a long time. I love the smaller circular cleaning brush. It seems like it would make it really easy to get in between your teeth and be super effective.

[This review was collected as part of a promotion.] I am not used to using a electric toothbrush so when I first used it it made my gums bleed a little bit. I have since learned to apply less pressure. It helped my teeth feel really clean but I still think I prefer a manual toothbrush.

[This review was collected as part of a promotion.] The Oral‑B iO Ultimate Clean replacement heads earn high praise for delivering a truly deep and thorough clean. Dental reviewers highlight its "Tuft‑in‑Tuft" bristle design and 16° angled bristles, which remove up to 100% more plaque along the gumline and reach tight areas between teeth. Great for the price and it's long lasting.
