Classic Oral-B heads with very good cleaning performance. The CleanMaximiser bristles that change color help you know when it's time to replace them, which is practical for everyday use. The cleaning is powerful without irritating the gums and the fit on the base is stable.
Nevertheless, their durability is not impressive. After 2–3 months of use, the bristles start to splay, especially if you brush harder. They are good, but not the most "hard-wearing" heads from Oral-B.

Pros:
Very good cleaning
Bristles change color to indicate wear
Stable fit on the base
Gentle on the gums

Cons:
Durability could be better
Bristles splay relatively quickly
Expensive compared to how long they last

Reliable and effective heads, but their lifespan is not the best. Good for daily cleaning, just expect to have to change them often.

Everything is fine, except that all the plastic rings in the package are white, so you can't distinguish the toothbrushes and have to use the old ones.

family pack = value for money

Very good heads, they clean effectively and leave a feeling of cleanliness from the first use. Durable and with a replacement indicator, an excellent choice for daily care.

In all of them the ring is white. If there are two identical toothbrushes you can't tell which is which

For its price, it is very good, it is much more cost-effective than buying two or three from the supermarket at a similar price. In terms of cleaning teeth, it could be better, so when you want something better you go for different brushes. These are the simplest ones you can find. They definitely do a better job than manual ones but they are not something amazing. The good thing is that it turns yellow and you know when you need to change it.

Those horns it has on the sides - supposedly to clean between the teeth - are a big lie. They just make it harder to place the toothbrush on the teeth, since every tooth is different. They apply more pressure and end up irritating the gums (I imagine over time also the enamel). I’m not giving 1 star, because otherwise the bristles are ok and last quite a while.

Packaging that is cost-effective with replacement heads that are high quality and effective in cleaning teeth. Despite the small size of the brush, they clean well and additionally do not "wear out" quickly. Recommended, especially if you find it at a good price...

Very good replacements. It is very nice that each of the 8 has a different little picture on it to distinguish in case there are more toothbrushes in the house.

When we find them at a good price, we buy several because in the end, none of the authentic ones clean as well and their price is quite steep

The originals cannot be compared to any other; their price may be a bit high, but I think they do the best job

Very good purchase, with 8 replacements you don't have to worry for a long time! The bristles on the brush change color when it's time to replace it.

Good choice, it just doesn't get deep enough between the teeth and the head wears out relatively quickly with three teeth washes per day!

We always use the authentic heads, we have been disappointed by others when we find them on sale we buy them they clean well

Very good! They penetrate better between the teeth and since I started using them, my teeth are whiter and shinier, while my gums bleed less.

If someone can get used to saying "black & decker" in their mouth, it can't be compared to toothbrushes...

Excellent.. they clean perfectly. I have the Oral B 3500 machine. I don't mind if the replacements are white. They clean better than the previous heads

Very good product. If you buy them at a good price in economical packages, and not from the s/m or the pharmacy, they have great value for money.

Indeed, it makes a difference in cleaning compared to other heads (I have tried the crossaction and trizone from Oral B), it cleans more precisely, penetrates interdental spaces, and reduces plaque formation, making you feel that your teeth are cleaner. However, it is harsher on the gums, which is expected in order to clean better. With gentle brushing and no pressure, there is no problem (after all, an electric toothbrush does not require pressure).

Very good replacement heads, they are just a little stiff, not particularly compared to the previous ones I had.

8 Brushes, with 4 different colored O-rings, to easily distinguish them from family members.
This is the second CleanMaximiser set I've purchased. It's worth it in terms of cleaning quality and durability. The key is not to press the brush on the gums and teeth because then it not only doesn't do the job, but it also wears out quickly. With proper use, each brush lasts comfortably for over 3 months.
The above are compatible with all Oral-B machines, except for the Pulsonic-iO.

The classic Oral-B brushes. Solid value.
The Precision Clean brushes are the ones that made Oral-B electric toothbrushes so successful and popular before the Cross action was introduced. They accompanied Oral-B electric toothbrushes as the Standard.
After using the Cross action for a while, I tried the Precision Clean again and they are exactly as I remember them, meaning exactly what you need without too many effects. They are effective in cleaning the teeth without irritating the gums.
Finally, they are now also the most economical, so it is one of the few times I can say that a product is both cheap and good.
Highly recommended.
