[This review was collected as part of a promotion.] A friend insited that her investment of two minutes a day has produced remarkable changes in her oral health. Alas, two minutes is the daily "goal" of these electric toothbrushes and it works. Ironically, the bristles on these "standard" refills seem to be more effective than specialized ones but they are all outstanding and last for months rather than weeks. They are easily installed, just as the brush is easy to use and far more effective than earlier generations of electric toothbrushes just as the discreet "landing" pad takes up scant space on the counter.

[This review was collected as part of a promotion.] I’ve been using the Oral-B iO Ultimate Clean Refills for a while now and I’m genuinely impressed. The value for money is great considering how effective and long-lasting each head is. When it comes to effectiveness, these refills leave my teeth feeling professionally cleaned every time — noticeably better than standard brush heads. The packaging is neat, secure, and easy to store. I also appreciate the durability — each head lasts several weeks without losing its cleaning power or bristle shape. Highly recommend if you want to get the most out of your iO toothbrush!

[This review was collected as part of a promotion.] First the iO brush is amazing! And these replacements are great. The brusheads are SOOO much better than the other electric toothbrush I had. It seriously makes a difference when upgrading to these. They recommend you replace your brusheads every three months so these are good to have handy.

[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.] The iO white brushes work well to clean my teeth daily. I have sensitive teeth and using the iO brushes clean my teeth thoroughly without putting pressure on my teeth to get the plaque off. The brush heads also are durable and will last a few months if you brush your teeth twice per day.

[This review was collected as part of a promotion.] The brush heads are comfortable, and leave my teeth feeling nice and clean. I use whitening toothpaste, and at this point I can't say whether these heads make my teeth look whiter as I've only been using for a couple weeks, but I like the heads and will continue to use whether they whiten or not. They're similar to other whitening toothbrushes, but they're designed for power toothbrushes, so I assume they'll work better than others. Give them a try, they work good and are comfortable, not too hard on my teeth or gums.

[This review was collected as part of a promotion.] Great replacement heads for the toothbrush. The one I've been using now is a perfect replacement for the orginal. Leaving your feeling refreshed and clean. If you don't have this brush and have been on the fence about getting one, get it, grab these replacement heads for a wonderful clean.

[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

Been using the iO7 for about a year and love it. What disappoints me is the brush head. Purchased the package of 6 from Sam's and every single one has broke within a month. There is a tiny piece of plastic with a magnet attached inside the head that breaks off. I do not drop them, or hit them against the sink. I am very gentle with them. I'm on my last brush head and needing to purchase more. Hope the Oral-b rep read this and take my suggestion back to the design board to make the internal pieces stronger. They are too expensive to have to replace every month.

[This review was collected as part of a promotion.] These brushes are very high quality. I use orabl b regularly and I find them better than any other toothbrush brand out there. They do what they say and go easy on your gums. They help to keep your teeth clean without being too harsh. The bristles are soft.
