[This review was submitted after receiving an incentive.] I was already really pleased with my new iO Oral-B toothbrush that I replaced my old brush with, so was delighted to be selected to try these brush heads for my brush by Supersavvyme. These Ultimate Clean heads take the experience to a whole new level as they are definitely cleaning my teeth even better and leaving me with a smooth, shiny feel to my teeth that is assuring me that I am removing any harmful residues from my teeth. This is especially noticable in the mornings when my teeth still feel clean after being asleep. These heads my not be the correct colour for my Calm pink toothbrush, but they are going to have to be purchased going forward as I don't want to lose the clean sensation on my teeth.

[This review was submitted after receiving an incentive.] These Oral-B Ultimate Clean heads came at the perfect time since I was due to replace my old toothbrush head. I've been using them with my iO handle and I can really feel the difference -- my teeth feel so clean and smooth after brushing, almost like I've just had a professional clean. They do a great job reaching those tricky spots, and even though the color doesn't match my purple toothbrush, I'll definitely keep buying them because the clean feeling is worth it. The only small downsides are the higher price compared to standard heads and that the head feels a little bulky in my mouth at times. But overall, they're excellent and I'd happily recommend them to anyone looking for a really thorough clean.

[This review was submitted after receiving an incentive.] This came at just the right time for me as I needed to replace the brush head on my iO. As it's a pack of 4, it's great value as will last approximately a year. I love my iO and these replacement heads give a real deep clean feeling after brushing. The built in sensor will warn if I've brushed too hard which comes in handy as I like to give my teeth a rigorous scrub so both they and my mouth feel fresh and clean. I love the colour change feature so k will never have to guess again when it needs replacing as it's not giving a complete clean. I would never go back to a manual toothbrush again and I thoroughly recommend these replacement heads for an iO

[This review was submitted after receiving an incentive.] Have been using the Oral B io electric toothbrush for a few months and was in need of a new brush head, so this came in perfect time. I used to be a manual brusher however was recommended by my dentist to switch to electric and will never look back. My Teeth feel cleaner and it's gentle on my gums, no bleeding anymore and easy to use and in your 2 minute brush time you feel that deeper clean then if I was to use a manual toothbrush. I change my head every 3 months so great for my full year to be covered so good value for money. Would highly recommend if you are looking for an electric toothbrush range and heads for this to be your everyday/first time use.

[This review was submitted after receiving an incentive.] I've been using the oral b io2 for just over 3 months and replaced the head it came out with the oral b ultimate clean. I could immediately feel the ultimate clean head gave a deeper clean without adding pressure to the teeth and gums. I have paired this with Oral B whitening toothpaste and the deep stains on my teeth from years of coffee drinking have dramatically improved. My teeth feel smoother never mind look cleaner. Using an electric toothbrush is a game changer for oral health and adding in the ultimate clean tooth brush heads have unapproved this further for me. The heads are expensive but you can purchase the value packs and it's still much cheaper than a dentist visit!

[This review was submitted after receiving an incentive.] Great brush heads that fit smoothly onto my toothbrush. They have a blue colour on them which fades to let you know when you need to replace the head. They have dual length bristles which help to get into all the hard to reach areas. My teeth felt really clean and smooth after using them and my mouth felt fresher. I would never go back to manual brushing as my teeth feel and look so much cleaner. Try them for yourself, you won't be disappointed.

[This review was submitted after receiving an incentive.] Brush head is easy to fit, the packaging is easy to open, no plastic fiddly brush head containers. It feels immediately more efficient and a firmer brush than my previous brush head for the IO that came with my first purchase. This is suitable for somebody who usually has a medium. This is not a soft bristle. It did not irritate my gums and there is a good pressure sensor on the brush to alert you when you press too hard. I can't honestly say that my teeth are whiter on day one however regular use at least twice a day will help and remove any stains or plaque from my teeth.

[This review was submitted after receiving an incentive.] I recently received the Oral B iO Ultimate Clean toothbrush head for free as part of the Savvy Circle project, and I'm genuinely impressed. Having tried other Oral B iO heads before, I can confidently say this one stands out. The cleaning performance is noticeably better, leaving my teeth feeling fresher and cleaner than ever. I'll definitely be switching to the Ultimate Clean head when it's time to replace mine. Highly recommended.
